Hi Thomas,
my main "resistance" to trying to upgrade or version rollbacks is
not the operation itself....
But this:
My garbage collect on hybrid, non-full SSD (NFS) datastores takes
at least 10 days (that's over 300 Tbytes of storage).
If there was a system to keep track of the garbage collect parsing
point before a reboot or upgrade would be a great thing, so that
it could then be resumed from the breakpoint.
If I update the PBS the garbage collects are closed and restarted
from scratch, ditto for a reboot.
