Best practices to change Profibus GSD in a S7 UPGRADE

Scenario: DeltaV 12.3 with a Profibus device (S7-200 to S7-1200) upgrade in progress.

I'm only upgrading the Siemens hardware. The conversion on Siemens was made maintaining the adress, byte offset etc.

In DeltaV, I need to maintain DSTs names.

What is the best Practice or the better way to do so ?

I know I have to be careful about existing modules with the actual DSTs in a case of renaming.
