We are maintaining SharePoint 2013 standard version in our production environment with managing large content of data in content databases.
We have one large content database with size 250 GB and consists of two site collections . So we planned to move one site with size 100GB to single content database.
After moving the site to separate content database, our DBA is planning to run maintenance jobs like shrink operation to reclaim the space from content database of initial size 250 GB.
Here is technet reference for DB maintenance activities link
Is shrink and other DB maintenance activities are supported from Microsoft end? Will these actions invalidate Microsoft support to our farm?
