When we replace TSM server from 32 bit to 64 bit, can we run dumpdb/loaddb from 32bit to 64bit server?
Running dumpdb/loaddb from 32bit to 64bit server may work, but we can not guarantee that it will work. The backup/restore DB from 32bit to 64bit server is fully supported.
In either case of the dumpdb/loaddb or the data base backup and restore, after upgrading from 32 bit to 64 bit we are aware of a problem which is reported in following APAR.
The simple resolution to the problem is once the server is started on the 64 bit server mark all filling volumes readonly and then perform a MOVE DATA operation on these volumes. This will fix the data base records that we know have a problem with the 32 bit to 64 bit upgrade.
