Before you upgrade the VMware Identity Manager virtual appliance offline, perform these prerequisite tasks.
Verify that at least 4 GB of disk space is available on the primary root partition of the virtual appliance.
Take a snapshot of your virtual appliance to back it up. For information about how to take snapshots, see the vSphere documentation.
If you revoked the db_owner role on the Microsoft SQL database, as described in https://docs.vmware.com/en/VMware-Identity-Manager/3.2/vidm-install/GUID-5B533EE2-8F6C-4716-A94A-8B7AA3F5BC75.html, you must add it back before performing the upgrade, otherwise upgrade will fail.
Add the db_owner role to the same user that was used during installation:
Log in to the Microsoft SQL Server Management Studio as a user with sysadmin privileges.
Connect to the database instance for VMware Identity Manager.
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 username.
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 username.
Take a snapshot or backup of the external database.
Verify that VMware Identity Manager is properly configured.
Confirm that a VMware Identity Manager upgrade exists. Check the My VMware site at my.vmware.com for upgrades.
