Data Migrations

Migrating data from one network storage device to another is an inevitable burden faced by all organizations at one time or another. Data migrations are necessary for any number of reasons including the:

  • Outgrowth of a server
  • Consolidation of multiple servers to a single server or SAN
  • Deployment of a new network operating system

Data migrations are normally huge IT projects, requiring the copying of each file from a source file server to a destination file server or NAS device. With terabytes of data to move, the process can certainly be tedious. It can also be disruptive to users who cannot access files that are targeted for migration.

But it’s the post migration work in a migration of this sort that really makes the process burdensome. Once copied, the metadata, time stamps, and most importantly, the rights pertaining to the migrated data are reset, making it necessary to reestablish those rights individually for each migrated file.

It’s no wonder that so many organizations running Novell networks have been hesitant to migrate from their NetWare servers. Unfortunately, most of these Novell customers are unaware that Novell Storage Manager can greatly alleviate the data migration burden by providing the means of automating data migration as well as retaining all rights metadata, and timestamps.

Novell Storage Manager

Novell Storage Manager automates the full lifecycle management of user and group storage. Leveraging the network directory (Novell eDirectory or Microsoft Active Directory), Novell Storage Manager automates a comprehensive set of storage management tasks based on events, identities and policies.

Directory events trigger actions that Novell Storage Manager takes, according to policies. Policies can specify:

  • Where to create user home directories and group directories
  • What specific files to provision inside the directories, along with the rights and storage quota settings
  • Where to move home directories and what rights and quota to modify when a user is moved in directory services
  • And much more

Novell Storage Manager Enables Data Migrations

Settings within a Novell Storage Manager policy can also enable the migration of home directories and group directories from a Novell source server to another Novell target server. For example, the policy setting can dictate where to move home directories residing on a NetWare server to a specific volume of an Open Enterprise Server 11 machine-and in the process, maintain all file rights, trustee assignments, metadata, and timestamp information.

Recently, Novell Storage Manager added Cross-Empire Data Migration. Cross-Empire Data Migration is a subsystem within Novell Storage Manager that migrates file system data between Novell and Microsoft networks, including their corresponding storage infrastructures and identity and security frameworks.

Through a wizard interface, Cross-Empire Data Migration quickly and automatically moves data based on a variety of scenarios, which include moving data for multiple users and groups directly to their intended locations across multiple servers or shares in a single operation-all while preserving important file system metadata.

Cross-Empire Data Migration supports three data movement types:

  1. User storage: Migrates data from a Novell home directory to a Windows home folder in accordance with your direction to migrate through either a source container or source file system path. You can also provision the Windows home folder as a part of this process.
  2. Collaborative or group storage: Migrates data from a Novell group home directory to a Windows group home folder in accordance with your direction to migrate through either a source container or source file system path.
  3. Direct folder storage: Migrates a directory based on distinct file system paths on both the source and the target networks.

The remainder of this article presents data migration scenarios and how Novell Storage Manager can be the means of simplifying each.

Scenario 1

Novell NetWare to Novell Open Enterprise Server 11 Data Migration

In this scenario, Novell Storage Manager is deployed in the Novell eDirectory tree of which both the source NetWare server and destination Open Enterprise Server 11 machine are members.

If the home and group directories you want to migrate are already being managed through Novell Storage Manager, you simply need to:

  1. Edit the Novell Storage Manager policy that specifies the NetWare server target path and change it to the desired target path on the Open Enterprise Server 11 destination server.
  2. Use the Enforce Policy Paths management action to initiate the migration of the directories from the source to the destination.

If the home and group directories you want to migrate are not being managed through Novell Storage Manager, you need to:

  1. Create a Novell Storage Manager policy specifying the current location of the directories you want to migrate as the target path for the policy.
  2. Use the Manage management action to catalog the directories.
  3. Edit the Novell Storage Manager policy that specifies the NetWare server target path and change it to the desired target path on the Open Enterprise Server 11 destination server.
  4. Use the Enforce Policy Paths management action to initiate the migration of the directories from the source to the destination.

Once Enforce Policy Paths has been run, Novell Storage Manager begins the process of moving home and group directories provided that all three of the following criteria are met:

  • The user to whom the home directory is assigned in not logged in to the NetWare server
  • The user to whom the home directory is assigned does not have a file open from the home directory
  • The Move Schedule allows the directories to be moved during this time of day

Case Study #1

Garland Independent School District

With an enrollment of over 57,000 students, the Garland Independent School District is the second largest district in Dallas County and one of the largest districts in the state of Texas. The district oversees 2 preschools, 47 elementary schools, 12 middle schools, 7 high schools, as well other non-traditional education centers.

Eric Feldman is a Network Services Engineer at Garland ISD and has relied on Novell Storage Manager for years to manage the thousands of student home directories hosted on the district’s Novell servers. Eric recently was involved in the migration of over 35,000 student home directories from NetWare servers to Novell Open Enterprise Server 11 servers. The process was very simple because all the district had to do was change the target path and then run Enforce Policy Paths.

Eric remarks: “I love Novell Storage Manager. It’s one of the best things we have here. It saves me some time almost every day.”

Scenario 2

Novell NetWare or Open Enterprise Server to Microsoft Windows Data Migration

In this scenario, Novell Storage Manager is deployed in the Microsoft Windows network where the network administrator uses Cross-Empire Data Migration to move the data for multiple users and groups directly across multiple servers and shares to their intended location. Furthermore, the migration maintains ownership, quota, and metadata information while transforming Novell rights and trustee assignments to equivalent Microsoft rights and permissions.

The following steps summarize the data migration process as documented in Chapter 9 of the Novell Storage Manager 3.0.x for Active Directory Administration Guide.

  1. Complete the prerequisite tasks.
  2. Create a Migration Proxy Account to enable communication between the eDirectory source and Active Directory destination.
  3. Create an Identity Map for associating users, groups, and containers that are the owners and trustees of the Novell network data and the corresponding data owners on the Microsoft network target.
  4. Use the Data Migration Wizard to perform any of the following data migration types:
    • User to user data migration
    • Folder to user data migration
    • Folder to group data migration
    • Folder to folder data migration

Case Study #2

HAMK University

HAMK University’s main campus is located in Hämeenlinna, Finland. Student enrollment is about 8,000 and university employs a staff of about 800.
For the past four years, the university has been relying on Novell Storage Manager to automate the management of their student and faculty network home folders located across multiple NetWare and OES servers.

In 2012, the university switched network operating systems from Novell to Microsoft. As part of this change, the IT staff needed to migrate the scattered 12 Million files located in the more than 8,000 home folders to a single NetApp attached storage device. The IT staff chose to utilize the Cross-Empire Data Migration subsystem of Novell Storage Manager 3.

The university was pleased with the outcome of the migration. ICT Specialist Sami Kapanen remarks, “NSM was able to migrate the files with ownership, date and trustee information included! This was a big thing for us.”

Conclusion

Whether it’s out growing or consolidating a server, moving data to network attached storage, or adopting a new network platform, at some point, a data migration becomes inevitable. Novell Storage Manager simplifies all types of data migrations through proven, easy-to-use tools and processes.

But migrating data is only a small portion of the file management capabilities of Novell Storage Manager. If you are not already using Novell Storage Manager to automate the creation, on-going management, and disposal of user home directories and group storage, we invite you to learn more by talking to a Novell reseller of visiting www.novell.com/storagemanager.
