Warning regarding need Bigint after 17.01 to 17.02 upgrade

Hello, I run nextcloud in a shared webhosting environment and have no ssh access to the server. Is there a way to trigger the conversion from php or SQL? edit: I just found the occweb app, but this seems to be not compatible with 17.0.2. It shows a warning. Are there other ways to get the columns converted? edit2: I was brave and used occweb Worked like a charm. Warnings are gone. Best, Lars
