 Description   

The  plan cache commands include:

  • planCacheClear
  • planCacheClearFilters
  • planCacheListFilters
  • planCacheSetFilter

All plan cache information is stored in memory only, and can be different on different replica set nodes.

Because of this, it seems ok for a tenant migration not to transfer any planCache information.
