Hi Experts

I am using exchange hybrid environment, I have one user for whom F1 license is assigned. 

can i migrate this user to Exchange Onprem or

can i change F1 license to E3 license, will user loose any data? which is better option for me.

@Roger Roger You can move to on-prem or assign E3 there will be no data loss, however it depends upon your requirement.

E3 offers 100 GB mailbox and F1 2 GB, so upgrading will not result in any data loss.
