How many time is needed to upgrade 2.0.6 to 2.08? Thanks.
The time to upgrade is minimal (less than 1/2 hour) unless you are using a third-party template that contains edits to Virtuemart files. In that case you should contact the template author to make sure your template will not break as a result of the upgrade. It happened to me recently and was a definite pain that took quite a while to fix.
