That's not really a bug, it's a choice, but....

I was looking for a solution, with JIRA, to put side (not delete) old closed issues. For our compagny, issues don't have to be deleted.
But, with the passing of years, there's a lot of issues, and the database becomes bigger & bigger.
Bulk move was a good solution for that, but in moving, the issue change his id (PKEY in database). It's a pity because the users knows their issue with the id... So, we can't use this functionnality.

Is it a problem for you to keep the old name?

For example, I have 2 project : A and B.
I have 3 issues in A : A1, A2,A3

2 in B : B1, B2

If I move A3 to B, the issue keeps his name. And the next one in A take A4 for name, the next one in B, B3 or B4 :
A : A1, A2
B : B1, B2, A3

If it's a problem, is it possible to show a column with the real ID in database (which don't change)...

Thank's for your help.
