Follow the steps below to upgrade Mobility 18.x to newer version of 18.x:
Download the ISO for the new version of Mobility 18.x from your Micro Focus Customer Center.
In a terminal, mount the GroupWise Mobility ISO using the following command:
mount <path to the Mobility ISO> /mnt
Browse to /mnt and run the install.sh.
Follow the prompts to upgrade Mobility.
Because of the changes that occurred between SLES 12 SP2 and SLES 12 SP4 (and the fact that there is not an upgrade path from Mobility on SLES 12 to Mobility on SLES 15), the recommended upgrade path is to create a new Mobility system:
Install your SLES server. It can be either SLES 12 SP4 or SLES 15.
IMPORTANT:If you install on SLES 12 SP4, you cannot upgrade to SLES 15 without breaking Mobility. We recommend you install SLES 15.
Install and configure the new Mobility 18.x system. Use the same settings you had in your old Mobility system.
Change your DNS record to point from the old Mobility server to the new Mobility server so users do not have to make changes on their devices.
Install your SLES 15 server.
Install and configure Mobility 18.x on the SLES 15 server. Use the same settings you had on your SLES 12 Mobility server. Make sure all of the users have been added to the new server.
Change your DNS record to point from the SLES 12 Mobility server to the new SLES 15 Mobility server so users do not have to make changes on their devices.
Upgrade your SLES 15 server to SLES 15 SP1.
During the SLES 15 SP1 upgrade, you are asked what you want to do about obsolete libraries. Select the option(s) to keep the obsolete libraries.
Upgrade Mobility normally following the steps in Upgrading Mobility 18.x. The Mobility install adds all necessary OS modules.
