I want to share some information:

-          TSM Server 5.5.6 was upgraded to TSM Server 6.3.3.100;

-          new instance of TSM Server 6.3.3.100 has been installed on new 
Power6 system;

-          all data was exported from old TSM Server and imported directly to 
new TSM Server;

-          upgrade has been completed successfully without any problems and new 
TSM Server is in production mode now;

-          export/import for big nodes was done in two steps: first with 
FILEDATA=BACKUP, then with FILEDATA=ARCHIVE (just to reduce export/import time 
and avoid skipping backups);

-          by mistake MERGEFILESPACES=YES was not specified during 
export/import of archive data;

-          as a result without giving any warnings or errors archive data was 
imported to separate set of file spaces slightly changed in comparison with 
backup file spaces (for example, for backup data /home/abcd - for archive data  
/home/abc1);

-          fortunately, it is possible to restore data from archives, but I 
have some questions:
Is it correct behavior of TSM Server or TSM Server should inform me about 
mistake?
Will new archives come to correct file system (I couldn't see any other 
possibilities, but any way) ?
May it create any other problems for me in the future?
Shall I open SR to IBM support?
