hi:
We use the ext2.2 to develop an application, and now we want to upgrade from ext2.2 to ext3.0 , could anyone tell me how to do it ? Thanks a lot.

I don't think there are many breaking changes in Ext itself but there will be if you use custom user extensions.

You just need to try - replace the Ext 2.x library with Ext 3 and perform some thorough testing.
