Production Upgrade Approach Challenge
We have upgraded our environment from Pega 62sp2 to Pega7.2 . We have upgraded from single schema to split schema in our lower environments.
We are planning to perform the upgrade on our Production environment.
We have current schema of Pega62sp2 lets say (rule+data) "X".
We will be planning to push the upgrade onto new schemas DataSchema "Y" and rule schema "Z".
Post upgrade onto production the environment will be tested for stability for a week. During that week the users will continue to use Pega62sp2 (schema "X").
Once we get a sign off on Upgraded environment we will require to move the delta transaction data which was created by user on previous week from schema "X" onto the new split schema "Y" and "Z".
Could you please suggest what's the best way to move the delta from single schema onto split schema ?
Would you recommmend anyother approach for PROD upgrade?

only thing which need to be consider is you can't migrate any cases created/processed during smoke test in schema X to Schema Y (data schema). Also you have to make sure that there are no new deployments are happening in Pega 6 during this pilot period.
There will be no deployments on Pega 6 environment. The only point being the delta which gets created on X (Pega6 schema) when Pega7 is being smoke tested will be moved after a week by running data only upgrade step.
After smoke test is done , if you are performing the data only upgrade on Pega 6 schema pointing to Pega7 rules schema will not cause any issues(Assuming that you are discarding the Pega7 smoke tested data schema) .
But the data created during the smoke test period on Pega 7 data schema will be lost.
