Strong +1 to what Nic has said.  If your DBA spots that we're missing an index we need, that's one thing (and please tell us!)  Altering the structure of the datamodel. changing the types and sizes of columns, etc. is just plain not a good idea.  Even if it works today, there is no telling what weird and wonderful headaches it will give you tomorrow.

Hmm.  You *really* shouldn't be changing the database like that.  It renders your system unsupported (and will turn round and bite on all your transfers and upgrades).  Please, undo it.

ok - looks like I got the problem. seems like my dev team had increased the table size in the source jira instance - so the xml file had data with more than 255 limits.
Edited the table limit in new db as well and restored successfully.
