Rolling upgrade with coprocessors

Hi all,
I'm using coprocessors with my tables and am wondering how I would perform an HBase rolling upgrade, since it seems like there are no compatibility guarantees for the coprocessor APIs. I'm guessing I would have to disable the table, alter the table to use a coprocessor compatible with the next HBase version, perform the rolling upgrade, then enable the table? Is there a way to keep the table enabled for this?
Thanks,Albert

Can you tell us the version of hbase you are using and the new version
which you plan to upgrade to ?

A bit more detail on your coprocessor would also help narrow the scope of
search.

Cheers
