I've tried to upgrade to from 8 to 9 but failed applying the hot patches. Once SDP was upgraded, a few pages didn't work. So I gave up and retored the sources and database.

Another alternative for me is not to upgrade, stop the old release and begin with the following TKT number in the new release.

My question is, Can I export all the TKT from 8.2 release and import them to the lastest one?

How can I do that? 

Thanks for your support.
