GAE 1.6.1
I am able to deploy but rollback gives the mentioned exception.

So, for rollback i use GAE 1.5.5 and it does fine.

Thus, there is an issue to do rollback using GAE 1.6.1

Also, Does it make any difference to the production if i deploy my app
using 1.6.1 and if required i rollback using  1.5.5 ?
I believe that production server must be using the latest version of GAE.
Right?


Thanks
Deepak
