I personally don't want you to blame us if anything goes wrong.
so please: do your own regression tests before converting on the
production system.

but we at linbit now gradually proceed to upgrade the directly
maintained by linbit clusters for our customers.

again, do your own benchmarks,
if you actually gain performance
from drbd 8 for your workload.

if you have a 24x7 production cluster,
you should have a very good
reason to change _anything_ at all.
 you know about Murphy and stuff...

upgrade is possible, but involves a cluster downtime.
you need to replace the module and userland tools,
and convert the meta data.

yes.
