Need help upgrading from Indico 0.94

Thank you for the link!

We have downloaded the 0.96.2 and got stuck at the installation:
The first step for setting up 0.96.2 (“setup.py upgrade”) requires a MaKaC configuration, but we don’t have a MaKaC installation in the migration environment.

Consulting https://getindico.io/legacy-docs/wiki/Admin/install/from0.html, it seems that a running 0.94 should be existing for the migration.
The thing is, we only have the database (indico.fs) and the archive folder available, so we do not have a running Indico 0.94. The database and archive are mounted on a CentOS 5 Docker container with Python 2.4, along with the Indico 0.96.2 files.

Do you happen to have a copy of 0.94 as well?
Or is there possibly a better workaround?
