Answer

Yes, under certain conditions, LIF migration is non-disruptive for SMB 2.0 and later. 

  • SMB 2.0 and 2.1, the use of durable file handles allows the session to reconnect without any impact to the application. 
  • SMB 3.0 and 3.1, will have a persistent open state that facilitates the non-disruptive behavior.

WARNING:

  • Durable/persistent file handles are exclusive to a single-file open.
  • Non-disruptive behavior might be affected when multiple users are accessing the same file.
