Administrators Migration from 1.2 to 2.0
1

Hello dear Indico administrators and developers.

I have recently tried a migration of Indico service. From ver 1.2 to 2.0.
I followed the steps from the guide:
https://docs.getindico.io/en/stable/installation/upgrade_legacy/

The script “indico-migrate” completed successfully. Lots of warnings came out however.

When I open “$INDICO_DIR/migration.log” then I see multiple messages which I don’t know how to interpret.
I tried to catch the repeating patterns. I came to those:

What do they mean? Where to get this info from?
Thank you.

It’s pretty normal that some of the old data in ZODB is messy. If you post the whole logfile (censor any PII first if necessary) we can tell you if there are any actual issues or if the warnings/errors are safe to ignore.

The history of Indico on our server started with ver 0.97.
Then continued to 0.97RC2 -> 0.98.1 -> 1.2.1rc2 -> 2.0.
I made a migration of Indico from ver 1.2 to 2.0 few days ago.
Then I removed personal information from the migration log.
migration_censored_2.log (107.3 KB) Please analyze it. Thanks.

I think you can safely ignore all of those warnings/errors.
