We are currently running ArcGIS Server 9.3 with the ArcGIS Javascript API 1.6 and we are looking at upgrading to ArcGIS Server 10.x. Are we required to upgrade the Javascript API as well?

I found some information about the requirements regarding ArcGIS Server when using the Javascript API 2.x. But not the other way around.
