[pve-devel] [PATCH manager v2 2/2] pve8to9: rrd migration: mention storage RRD files for which automatic migration doesn't work

[Fiona Ebner]

The RRD migration tool currently has the limitation of not migrating
RRD files for storages with a '.old' suffix. Mention the list of such
storages below the RRD file list and migration command so that users
can adapt before executing the migration command.
