[cisco-voip] Restoring 4.1(3)sr5d Publisher?

[Dane]

We had a drive fail on our publisher and had someone swap it out last
night.  Well it seems they made a couple of mistakes and left me no
option but having to rebuild and restore now.

Were running 4.1(3)sr5d and have a current BARS backup.

Problem is all the media we have is some what old so I am having to
install and upgrade and upgrade and upgrade to get back to where we
were.

My concern centers around the fact that this is the publisher that is
down and having to be rebuilt using older media and then upgrading to
get back to the point we were.  Is there a risk in corrupting or
interrupting the subscriber that is currently operational and running
everything?  I am afraid of the publisher coming back online too early
during the process and somehow overwriting information on the
subscriber before the publisher is fully built.

My TAC engineer isn't familiar with the 4.1 release and windows side
of things.  Currently the plan he suggests based on the media we have
available is to install 4.0.2 (from media) offline (unplug cable),
then upgrade it to 4.1(3), then upgrade to 4.1(3)sr5d, then install
BARS from that version of CM and do the restore of the BARS backup
data.

Does this sound right to others?
