Upgrading or Downgrading an Expressway VM
Before you begin
Profile Information is Removed from Backups
From X12.6, Expressway backup files do not include system profile information (ProfileID value). This is to prevent a known issue with unexpected changes to sizing if a backup is restored across a different sized deployment. Therefore, device profiles are unaffected by backup and restore operations. Refer to Bug ID CSCvs59766.
Procedure
Step 1 |
Take a backup of the smaller (or the larger for downgrade) VM configuration. Use the Expressway’s backup function, not the VMware snapshot. |
Step 2 |
Install and deploy the new, larger (or smaller for downgrade) VM as described in this guide. |
Step 3 |
Restore the configuration of the (old) smaller (or the larger for downgrade) VM onto the newly deployed VM. Note that profile information will not be included in the backup/restore. |
