Thread:Project:Support desk/Problems upgrading to Mediawiki 1.19.1/reply (2)

hi, great to hear you were able to migrate easily. i have the same task planned in couple weeks or so. we are running with 1.15.1 and wanna move to 1.19.1. what are the preparatory work i must do before starting to deploy(untar) the 1.19.1 on top of it? how about the mysql version differences ? do we have scripts to make the db schema changes to the database as well or it has to be manually done? how did u handle it at your site ? can you just brief me so that it will be much easier for me to sail through without any errors ? thanks a lot for your help.
