I recently tried to perform a platform migration from 4.0 NT to 4.2 Windows 2000, unfortunately I had nothing but problems when I put the server into service, namely I couldn't make any changes to the Dbase. After many days of trial and error, Nortel recommended re-keying the Dbase in by hand. I have just found that I can't add anymore CDNs or change any of my Parameters in the Historical Stats window even though I am licensed for more than are configured. I did a solution search on Nortels website and all threads seemed to lead to database corruption, reload SCCS. I've already done this 4 times.....Anyone?
