Subject: Re: [galaxy-dev] Can't downgrade database.

you need to run the downgrade command (sh downgrade --version=129) from the folder with the newer Galaxy. The old one does not have the downgrading scripts.

Thanks for using Galaxy.

Hello everyone,

I tried to download a newer version of Galaxy (I had 15.10 and pulled 16.01 in a different directory) and now for some reason in my old working directory I get the error:

Your database has version '133' but this code expects version '129'.

Please backup your database and then migrate the schema by running 'sh upgrade'.

when I tried:

sh downgrade --version=129

I got the error:

I checked earlier posts stating  that i need to remove all .pyc files before downgrading. I did just that but nothing worked.

Any ideas?

Thank you in advance,
