You can move devices containing NSS volumes between NetWare 6.5 SP8 servers and OES 2018 SP2 servers. When you move an unshared device to a different server, you must decommission its volumes in eDirectory for the current server, then recommission them for the new server.
For shared NSS pools and volumes, OES Cluster Services provides this service automatically during a rolling cluster conversion from NetWare 6.5 SP8 to OES 2018 SP2. For information about converting shared pool cluster resources and service resources, see the OES 2015 SP1: Novell Cluster Services NetWare to Linux Conversion Guide.
The NSS media upgrade for enhanced hard links support is available for the following operating platforms:
NetWare 6.5 SP4 and later
Novell Open Enterprise Server 1 Linux and later
The media upgrade is not available on OES 1 Linux, NetWare 6.5 SP3, and earlier versions. You cannot move a device that has been upgraded to the new media format to a platform that does not support it. For information about the media format upgrade, see Section 5.0, Upgrading the NSS Media Format.
Different pool snapshot technologies are used for NSS pools on NetWare and NSS pools on Linux. You can create pool snapshots on either platform, but the snapshots are unusable if you move the devices cross-platform and are invalid if you move the volume back.
WARNING:Before moving a device cross-platform make sure to delete any existing pool snapshots for all pools on it. You might not be able to see the original pools on the Linux platform if you do not delete the snapshots before moving the device.
For information about differences to expect when using NSS, see Section 8.0, Cross-Platform Issues for NSS.
