Thank you for your replies. I appreciate it.
So far I have started on a Virtual Ubuntu 10.0.4 LTS with Moodle 1.9.7. Its a mirror of our production server. Did a mysql dump and the virtual is the same as the production.
From reading the upgrade paths from Moodle 1.9.7 is to go to 2.0 then 2.2 then 2.7. I read all the upgrade doc's and replaced the program files (/var/www/moodle with the 2.0 version. Copied the 1.9.7 config to the new moodle 2.0. I get a version mismatch error when going to http://ourmoodlesite/moodle/admin. Section_links can't downgrade 2007101511 > 200710509.
Is this error related to the "+" part. Our production 1.9.7+ Build 20091215 while the mirror test site is 1.9.7 20091126
