I have two NW6.5SP7 servers.  ServerA used space=200GB with 26GB free+purgeable remaining.

ServerB has 700GB free and I want to copy all data from A to B.  

Would ArcServe restore or NCOPY be the best method?

No, your best method is to go to www.novell.com/downloads and search on the Server Consolidation and Migration tool (SCMT.EXE is the download file).  Put it onto your workstation that has been hard-coded at 100mbps/full duplex.  Hardcode both your source server and target server to 100/full as well (using INETCFG).  Doing the hard coded setup eliminates auto-negotiate packets and will greatly speed up the copy process.

This utility also preserves all user rights, file attributes and ownership as you copy/consolidate.

You'll use the "Server Consolidation" side of the utility instead of the "Migration" as you simply copying files from a volume on server 1 to a similiarly named volume on server 2.

Be sure that both servers are registered in SLP with the SMDR service.  Type display slp services on the server console of both and look for the SMDR: <server name>

If you need further help.  Please post back.  I use this utility all the time and have tremendous success with it.

I dl the tool and smdr services results below.  I want to migrate the DATA volume of AUBURN to the DATA volume of AUBURN2.  I would like to switch names on the servers; does SCMT make that easier than doing it myself??  Thank you for the tip; it looks good.  

 service:smdr.novell://192.168.2.6:413/AUBURN2        
 service:smdr.novell://192.168.2.2:413/AUBURNGW      
 service:smdr.novell://192.168.2.3:413/AUBURN        
 service:smdr.novell://192.168.2.11:413/AUBAK

I changed line speed on both to 100FULL as you suggested.  What about Receive Buffers?  Would a value higher than the current 200 be advised?

I don't typically change anything than the speed.  Once I did a job that had me move 33GB of data using the tools and where I was able to nail the speed/duplex.  It took about 3 hrs to complete I did another job a few days later where I couldn't nail the cards on speed/duplex (so auto-negotiate was present) and 35 GB took 16.5 hours.  I didn't change the receive buffers or anything else.

In the utility, you'll see your source server AUBURN on the left and AUBURN2 on the right.  You'll drag folders from the DATA volume on AUBURN over to the DATA volume on AUBURN2 and it will create a "job" for each folder structure.  When you're done with all of your "dragging" of folders there is a button in the toolbar to verify.  It will verify a bunch of stuff, most of which you just click Next to go by.  If everything checks out, you'll get a "proceed" button.  The first time verifying a job it will likely want to replace some of the NLMs involved.  Let it do that, go out to each server console and unload/reload the NLMs the utility replaced and then go back and re-verify the job.

I do the first pass in the middle of the day.  It skips over open files.  I do a followup pass in the evening when everyone else (those who lead normal non-IT lives) are at home and get anything "newer" (which is one of the checks verify does).

When you're all done, you can rename the server manually.  Post back and I can help you with that too.

Critical errors, six of them: "Error opening connection to SMDR."  appears to be problem on AUBURN2 because there is a MIGERROR.LOG file on that server with six of these errors:

0xfffefff0    NWSMListTSAs            AUBURN.*

AUBURN2 had later dates for TSAFS and TSANDS so I copied both over and reloaded, but TSANDS wouldn't load due to UNRESOLVED so I reloaded the older TSANDS.NLM and ran job again but same same.

I put entry for AUBURN in AUBURN2 hosts file and yes indeed SCMT works great.  Scott, thank you for your help; much appreciated.
