If you need to downgrade our modules, you don’t get a guarantee from our side, that is is working as expected.

We take care to make downgrading possible, but don’t especially test this in different environments.

How to downgrade?

This is as simple as a manuell update. Download ZIP file from our shop and upload them to your VtigerCRM directly within Module Manager.
Vtiger would call it “Update”, but you get the older version after the “Update” is finished.
