Archive in Common Server and change the expiration date

[soniab]

Hi

We are migrate from Spool File Archive to Common Server without the IBM migration. We respool from Spool File Archive and archive the spool created in Common Server.

A document archived the 20050101 must expired 7 years later (20120101). How I can setup the expiration date proprely in Common Server?

Thank in advance.
