Redash migration from 0.11.*.* version to 8 version

Hello everyone,

I’ve a question here, I’ve been trying to migrate Redash database from old version of 0.11.* to fresh version 8+.
So far I’ve only came to learn how to break the server in number of different ways…

Closest post that I’ve found, that covers part of my problem is this:

I’ve tried to follow it closely, but seem to miss something along the way. Simply put, it doesn’t work for me.

I’ve successfully dumped the Redash db via pg_backup into a .dump file. Yet I cannot seem to restore my data correctly on v8 machine.

Would there happen to be a thep by step solution somewhere in docs on how to restore? Maybe I’ve missed something obvious?

I’ve been digging at this problem for number of days now, I’d highly appreciate some help.
