I break a SnapMirror relationship (involving a FlexGroup volume) between SITE "A" (PROD) and SITE "B" (DR) and release the mirror. Note: I do not delete any snapshots from either side
I then create a new relationship between SITE "A" (PROD) and SITE "C" (pre-PROD) and complete the initialization.
The data is then cut-over and SITE "C" is now PROD.
Should I be able to then create a new relationship and RESYNC between SITE "C" (PROD) and SITE "B" (DR)?
Or will I need to re-initialize?
See The Solution
Re-sync will not work. You will need to re-initialize from C to B.
As I understand your plan:1st : A(PROD) ---------> B (DR) [Both A & B will have common-snapshot for their respective relationship, hence sync & re-sync is possible]
2nd : A(PROD) --------> C (pre-PROD) [Both A & C will have common-snapshot for their respective relationship, hence sync & re-sync is possible]
3rd : C(PROD) --------> B (DR) [No, There is no-common-snapshot between C & B to perform resync/sync] = re-initialize will be needed.

Thank you. And just to expand this for my edification... had the destination at "C" been a cascade from "B" (and not a FlexGroup volume), there-synch would be possible?
