I think the main issue is how you can/will move your lists. There are basically two approaches to relocate a server, you can create the new server, move lists one by one, and then close off the old one, or if you're using the same operating system you can just move the whole disks/directories in one block. This is usually much faster but in that case you have to make sure that traffic isn't lost. I guess in that case I'd create a "storage bay" account on the target system and have RSCS reroute all files to that account, and MAILER forward the mail similarly, to the same userid on the new system. I'd set up MAILER on the new system to think LISTSERV is the storage userid, and have mail for LISTSERV forwarded to the storage account as well. Then I'd have all the time I need to move the server, and I could still send it test messages and everything to make sure the new setup is working, and I'd simply CP TRANSFER the files when done, first a few and then the whole bunch. Hope this helps. Eric
