Migrating an Archiver Appliance to a new machine

[Windsor Tanner via Tech-talk <tech-talk at aps.anl.gov>]

Greetings,

We're currently in the process of migrating our Archiver Appliance to a 
new VM and
have a few questions regarding how to properly copy over the data to the
new installation. The setup on the new machine is identical to that of the
current (old) one, i.e. data being archived to 
/arch/{sts,mts,lts}/ArchiverStore/...,
 the same IOCs, policy settings, and so on.

Should the data first be consolidated into the long term store on the 
old machine  prior to
moving it, or would it suffice to copy it as is and then resume 
archiving on the new machine?
Also, is it necessary to shut the archiver down completely on the old 
machine before moving data,
or is it enough to just pause the  PVs beforehand in order to freeze the 
.pb files?
Thanks in advance, we'd be grateful to learn of your experiences on this 
issue.
