@tbielejeski - continuing the conversation here.

For reference, you need not have run mattermost db migrate, the migration happens automatically on start.

I can see some errors in the logs. @noxer - would you be able to assist @tbielejeski with this one?


I suspect you mean me :wink:

@tbielejeski I noticed that your path separators are backwards. They should be / instead of \. Go interprets the \ as an escape code, hence the first error. The same can be seen in open migrations\mysql, there should be a / here.

Which operating system are you trying this on?

lol … yeah sorry hard to remember so many usernames :stuck_out_tongue:

We are running on Windows 2016 OS

Natively or inside a WSL container? Native Windows installations are not really supported…

Runing on native windows OS. Actully I reverted back and did a version by version upgrade process and the data migrations were all performed. so seems a jump from the LTS 6.x to LTS 7.x does not work well
