We got recommendation from Infra team for disk host cache configuration change on Sitecore SQL database servers. Basically change is Disk host caching should be read\write for OS, read\only for data and none for log disks and application shouldn't write on disk which means we need to stop IIS for CM and CD sites. Along with this we also need to stop xconnect collection, marketing ,refdata , xconnect collection search websites so that these sites shouldn't write anything to xDB while Infra activity is being progressed.
Do you think stopping and starting these IIS websites is okay OR this activity leads to unexpected issues since this is complete XP system and all these components are connected to each other.
Version: Sitecore 9.3
