Fortunately, there is not much to say on this so far. During our testing, and during IBM development testing, there were no significant problems discovered causing migration failure or malfunction of OS/2, MPTS, TCP/IP, or File and Print services. Testing environments included different fixlevels on OS/2 LAN Server 3, OS/2 LAN Server 4, OS/2 Warp Server 4, and OS/2 Warp Server SMP.
