Hello all,
I'm following up on a thread that was started before which recommended that I (the aggregation module developer) provide an update path for the abandoned aggregator2 users. This is now complete :-) I don't think there's any need for me to remind developers to BACKUP everything (site + database) before attempting such a jump. You will find the details at the project's page and more details in the README file accompanying the module.
