Re: Upgrading from 7.4 to 8.2

Dear Rickard,

The jump from 7.4 to 8.2 is rather big.
I would suggest doing just a dry run by  dumping
the database schema without data and restoring it
into 8.2 database . this can be time saving in detecting
possible problems in migration.

in case there is some non trivial problem
you may take intermediate path of upgrading
7.4-->8.0.x-->8.1.x -->8.2.0
where x denotes the last minor release of a major
release.

regds
mallah.
