[On behalf of Kamran] Getting DIE ( Data Integrity Error) in PROD
We never got this error in older version. We already ran AE Version as well. There are 4 appservers (A, B, C and D) for failover and load balance. We dont want to bring down all of Production for Migrations.
One thought was to
1) Bring down 3 application servers (A, B and C) during a non-peak time,
2) Copy the project to production,
3) Bring up 2 (A and of the 3 downed application servers
4) Bring down the 4th application server (D)
5) Copy the cache from the still down application server (C) to the 4th application sever (D)
