Prepare for ArcGIS Enterprise 12.0: Script to identify caches stored in the deprecated tile cache data store

[Sarah_Hanson]

ArcGIS Enterprise 12.0 will include the removal and retirement of many features, including the ArcGIS Data Store tile cache data store. Organizations must plan to migrate all hosted scene service caches from the tile cache data store to the object store before upgrading to ArcGIS Enterprise 12.x.

This blog provides comprehensive information about the deprecation of the tile cache data store and the tools introduced in ArcGIS Enterprise 11.4 and 11.5 to help migrate caches to the object store.

For organizations using ArcGIS Enterprise 11.3 or earlier and looking for a simple way to determine whether they have caches stored in the tile cache data store, a Python script is available. The script and detailed instructions can be found in this Knowledge Base article. Please share your feedback and questions in the comments below.

The only thing I'd add here is that the Object store DataStore type wants more memory to run effectively than the TileCashe store does. 

It was not easy for me to find this spec change, but it is in a Notes section for datastore types.

So for us, we were running TileCache data store on an 8-core 32Gb datastore.  When I converted this server to use the ObjectStore, I noticed right away that it used 50%, or 16Gb of RAM while at rest with nothing on it.   

I finally located in the specs for this data store type that it wants 32Gb minimum free to support QueryCache and TileCache, and 32Gb free to support its java.exe windows processes.

For us, this meant we needed to increase the storage size of the C Drive of our VMware virtual Windows 2022 server from 100Gb to 250Gb in order to double the memory to 64Gb.
