Thread:Project:Support desk/How to run the update script/reply (6)

Whatever you do now: Since you don't have an unbroken backup, you have to live with the fact that you possibly have -maybe partly- broken records for some pages/users.

Apart from Ciencia's idea another option would be to upgrade back to 1.19 again and to continue using 1.19. All user accounts and files and so on will then still be there.

Both options are not ideal. But given the available possibilities I would upgrade to 1.19 as soon as possible. I guess you one day want to do further updates anyway (because of security wholes, or extensions, which are only compatible with newer versions or whatever). The longer you continue working with 1.16 while you can no longer use the Update Wizard for updating to 1.19, the more things might get broken.

Afterwards make this old extension compatible with 1.19. That is way better than messing up your wiki even more. ;-)
