Hi Graham, you could probably encapsulate your database-calls with <dtml-try> ... <dtml-except> <dtml-return maintenance_page> </dtml-try> HTH Tino Wildenhain Graham Chiu wrote:

Best way is to mirror your database before doing any changes on the tables. Then you can switch your zope with a session to the copy of the database. join session, change all database-connections (or only the one you are using) and commit the session. Nobody will notice anything during this.

I am thinking of upgrading the server software which would mean shutting Interbase down for a couple of hours. Just wish Zope had a way to redirect within the standard error message.

Eg. if 404 error - redirect to maintenance page.

But I don't think that works.
