Upgrading Omnissa Access Offline

To upgrade to version 24.12.x, you download the upgrade package and apply it to the existing appliance using a script. Before you begin the upgrade process, make sure that you complete the prerequisites.

Prerequisites for an Omnissa Access Offline Upgrade

Before you upgrade to 24.12.x offline, perform these prerequisite tasks.

• Make sure that you have a backup or a snapshot of your virtual appliance. For information about how to take snapshots, see KB article 2032907, Managing snapshots in vSphere Web Client.

• Take a snapshot or backup of the external database.

• If you revoked the db_owner role on the Microsoft SQL database, you must add it back before performing the upgrade, otherwise the upgrade fails. Add the db_owner role to the same user that was used during installation:

  1. Log in to the Microsoft SQL Server Management Studio as a user with sysadmin privileges.

  2. Connect to the database instance for Omnissa Access.

  3. Enter the following commands.

     If you are using Windows Authentication mode, use the following commands:

     USE <saasdb>;
     ALTER ROLE db_owner ADD MEMBER <domain\username>; GO 
     

     Make sure that you replace <saasdb> with your database name and <domain\username> with the relevant domain and user name.

     If you are using SQL Server Authentication mode, use the following commands:

     USE <saasdb>;
     ALTER ROLE db_owner ADD MEMBER <loginusername>; GO 
     

     Make sure that you replace <saasdb> with your database name and <loginusername> with the relevant user name.
