I am currently planning a roadmap for future software upgrades for our organization. I have found the documentation for product life cycles for ArcGIS Enterprise, ArcGIS Server, Desktop, Pro, etc. using the following documentation
https://supportuat.esri.com/en/Products/Enterprise/arcgis-server/ArcGIS-Server/10-8-1#product-suppor...
However, I cannot find anything for the Enterprise Geodatabase. In the past I have always kept ArcGIS Server and the Enterprise Geodatabase version the same but, I can't seem to find anything that points to version dependency between an Enterprise Geodatabase and other products.
We are currently on 10.8.1, but some datasets may not be ready to upgrade to the next Enterprise Geodatabase version by the mature support timeline for Server or Enterprise (+/- August 2024), such as Geometric Network.
