Hi Bill, It's going to depend a lot on your network speed, some on the type of disk you are using for your databases, and maybe a little on the CPU speeds of your servers.
We have not yet migrated any of our production TSM instances, but we have been doing some dry-run performance tests. On one instance having a 680GB database, we ran three tests, as follows: Test 1: source (AIX) database on 15K target (Linux) database on SSD source server having 10Gbs ethernet target server having 1Gbs ethernet Elapsed time was 15 hours, 45 minutes Test 2: source database on SSD target database on SSD source server having 10Gbs target server having 1Gbs Elapsed time was 12 hours, 32 minutes - SSD helped some Test 3: source and target databases both on SSD source and target servers both having 10Gbs Elapsed time was 6 hours, 20 minutes - quite a bit better due to the 10Gbs ethernet Statistics & dry-runs were done by David Beardsley, here at Cornell. ..Paul At 12:57 PM 7/29/2016, Brian G.
