We currently have a snapshot policy assigned to a number of volumes that keeps 180 daily and 52 weekly snapshots (in essence giving us 1 year of retention). Now that we are on 9.4, we want to switch that to 365 daily and 0 weekly snapshots. If we change the snapshot policy to that (365 daily and 0 weekly), will the weekly snapshots be automatically deleted?
We have a case open and the support engineer says they will be deleted, but that isn't what we recall happening on the 7-Mode side. He says the only way to preserve them is to leave the policy at 365 daily and 52 weekly and then in 1 year make the change.
