Upgrad 3.23 to 5.7 (1 reply)

Hello all together,

I have a big problem and hope that I am right in this forum thread and you can help me.

Problem description:
We have an old server with a SQL 3.23.58 and need to upgrade it to version 5.7.
I have invested a lot of time in the meantime but unfortunately I can't find any helpful documents/forums/documentation.

Has anyone done this before and can summarize for me how best to proceed?
Does anyone have the version files of each major version?
