The documentation for TSM 6.1 notes that recreating a TSM server

Our own TSM environment writes copy pool volumes to TS1120 drives
in a 3494 library. Our hot site vendor can only supply TS1120
drives in a TS3500 library. If we have to recreate our TSM server
there are upgrading to 6.1, we will obviously need to change the
library definition in the device configuration file, but I have
not found any documentation explaining which options have to be
included or whether there are any restrictions on the order in
which the options appear. We will need to change tape drive
definitions. The changes resulting from different special file
names are straightforward, but it is not clear whether we will
need to make changes resulting from the change in library type.
In particular, it is not clear whether we will need to specify
an element number for each drive. The documentation for the
device configuration file indicates that we will need to add
comment statements indicating volume locations, but does not
specify the format of the comments, or their location in the
file, or whether there are any restrictions on the order in
which different volumes appear.

Is there any documentation available that addresses these issues?

I guess not. Your situation is a bit different, but in short, you'll
need to change your devconf file to reflect the scsi lib rather than a
3494. Yes, that would include element addresses for the drives as well
as for the media in the lib when you do a database restore.

This is by no means new for TSM 6.1, you'll have to make the exact
same steps when you restore a 5.5 server at your DR site.

The 'easiest' way to do this is define one drive in a manual lib, do
the tape handling manually when restoring the database and then, when
the server is running, define the lib anew when you have a functional
server.
