Error while importing db to v1.3.8 from v1.2.2

http://continuum.apache.org/docs/1.3.8/installation/upgrade.html
I m following the above guidelines to upgrade our current continuum version(v1.2.2) to the latest stable version (v1.3.8).

I was able to successfully export the db from previous version but facing issues while importing the same into the new version(v.1.3.8).
It looks like that few columns are dropped in the new schema which is causing the issue - please let me know if we have a fix for this or is there any other workaround.

Below is the stack trace of the error that I see:
