https://community.esri.com/t5/arcgis-enterprise-questions/upgrading-enterprise-geodatabase/m-p/1628327#M42540 <P>I'm in the process of researching upgrading our Enterprise Geodatabase. Historically, our current 10.7.1 geodatabase wasn't well maintained, so we are looking at taking a start from scratch approach instead of cleaning up and upgrading our currently EGDB.</P><P>That being said, we are currently on Enterprise 11.4, with hopes to upgrade to 11.5 in the fall/winter season. Is it possible to run 11.4 on an 11.5 EGDB, if i just create a new EGDB through Pro 3.5/EGDB 11.5? Or would it be best practice to create the EGDB with match the current Enterprise/ArcGIS Server Clients that we are running?</P> Mon, 30 Jun 2025 14:05:11 GMT YRP_GIS 2025-06-30T14:05:11Z https://community.esri.com/t5/arcgis-enterprise-questions/upgrading-enterprise-geodatabase/m-p/1628327#M42540 <P>I'm in the process of researching upgrading our Enterprise Geodatabase.

With that being said, it isn't a requirement.</P><P>However, if you're going to mix and match versions, I'd recommend your EGDB be at the lowest version of the various software you're running. So in your case, it would be a 11.4 EGDB since you're running Enterprise 11.4 (even though you're running Pro 3.5). That will ensure that your EGDB is fully supported by all your ArcGIS clients.</P><P>Generally, I believe an 11.5 EGDB will work with Enterprise 11.5, but any new EGDB functionality released in 11.5 might not be compatible with Enterprise 11.4. But like I said, it's recommended that you keep your EGDB and all ArcGIS clients at the same version.</P> Mon, 30 Jun 2025 14:14:29 GMT https://community.esri.com/t5/arcgis-enterprise-questions/upgrading-enterprise-geodatabase/m-p/1628341#M42541 RyanUthoff 2025-06-30T14:14:29Z
