We are aware of this...
However, this process is recommended to do once you are ready to migrate from VSC to Snap Center 4.0 which we are not yet ready.
We were trying to evaluate Snap Center 4.0 along the sides of VSC before we jumped ship in the same vCenter. We were toldat first that this would be OK after recommending to upgrade to P1D6. Turns out it only made things worse for us.
Later, I found a posting in actual NetApp documentation that VSC 6.2.X is incompatible and not supported to co-exist with Snap Center 4.0.
When brought this forward and then moreconfusion started to arise from it all.
Eventually we simply yanked Snap Center 4.0 and restored our VSC to be able to actually manage it.
At this time, we are re-evaluating our options and it seems like we will be building a new vCenter with a migration plan for VSC to Snap Center 4.0.
That way, we can at least retain our existing VSC backups while we migrate to Snap Center 4.0 in the new vCenter.
