I did just what you're asking for a client last month. You can
backup-restore the DB between 32-bit and 64-bit with no problems. I
was fortunate with this conversion that the DB and LOG volumes were on
SAN attached disk. So we just mapped the volumes over to the
new 64-bit server with the same drive letters and TSM came up no
problems.

Before I did this conversion, I opened a PMR with Tivoli support and
they told me that only the OS matters. 32/64-bit doesn't.

I do restores at Sungard where I only have a 32-bit processer and the
home TSM server is 64-bit. And have no problems.

Subject: Migrating to 64-bit Windows OS

Some of our servers are going end-of-life this year and we will be
replacing them with new servers that will have the 64-bit version
of the
W2K3 operationg system (instead of the 32-bit version that we had
prior).  Two questions:

1.  Is it possible to backup the 32-bit version of TSM (full db backup)
and then do a point-in-time restore to the new server which
has the 64-bit version of TSM installed on the 64-bit OS.  I know that
going from different OSs is not possible (ie UNIX to
Windows), but can it be done from 32-bit Windows to 64-bit Windows?

2.  If the above is not possible, are there any issues running a 32-bit
version of TSM on a 64-bit OS?
