@MadhusudhanRao the trick for volume permissions is that the same user running the FSC service needs to also be the owner and have full rights to the volume and files. It worries me a little that you are using a local\infodba account and not a domain user account but if you are single server then its okay. If your environment is distributed across several servers then this can become an issue as each server will have its own unique account which makes setting permissions nearly impossible.
So make sure that the migrated server has its own local\infodba set and not the permissions from the amazon server local\infodba. Clear the cache and restart the service if you make permission changes to the files.
