Hi @juliegoff! Welcome to the ODK forum. When you get a chance, please introduce yourself here.
Given that you are in the middle of a campaign, you might want to consider migrating to ODK Cloud.
It’s the same Central software that you'd install on AWS, but we do all the hard work for you. That includes regular updates, daily backups, uptime guarantees, enterprise security, and guaranteed support from the core team on any issues.
And if you choose our Professional plan, we'll take care of migrating data from an existing Aggregate server for you.
