Hi there, I just did a successful update from Moodle 1.9.8 all the way through to the current 2.5. Took all day but it did go smoothly - the only thing is now we have some strange looking users in the list of users. I've attached a screen cap here.
I just need to know could this be users that have been corrupted in the update and if so, is it okay to delete them.
I have the old database backed up, and all the old certificates so we don't necessarily need the records... I'm just curious to how or why they got there!
