Before you upgrade the VMware Identity Manager virtual appliance online, 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.
Verify that the virtual appliance can resolve and reach vapp-updates.vmware.com on ports 80 and 443 over HTTP.
If an HTTP proxy server is required for outbound HTTP access, configure the proxy server settings for the virtual appliance. See Configure Proxy Server Settings for the VMware Identity Manager Appliance.
Confirm that a VMware Identity Manager upgrade exists. Run the appropriate command to check for upgrades. See Check for the Availability of a VMware Identity Manager Upgrade Online.
