Epicor and ECM Upgrade Versions

[gpayne (Greg Payne)]

The thing you need to determine is the solr version and take the steps in the thread below and uninstall solr and remove the solr folder and reindex if you are below 9

ECM Upgrade Down Time v22.2.109 to 23.1.58

The upgrade is in reality a complete uninstall/reinstall of the ECM server components. Yes, ECM will be unavailable until the process is complete. But then it’s completely available, immediately. SO if you want time to test things before the users get in, then you need to figure out how to communicate with them that you need time before they start working again.
