Hi
I am looking to migrate 5 mailboxes from exchange 2010 on premise server to
office 365 in the cloud, and eventually remove/ shutdown my exchange server and work cloud only .
Some things to take in mind: one of my users has a 42 gb mailbox...
What is the best way to migrate ? should I use third party software - like bittitan?
And how can I deal with the large mailbox of 42 gb?
Thanks
Omer

For this kind of migration the best option is to use Cutover process described on the documentation.
The process is strait, and is the best solution to your migration.

Hi @orrtech,
A PST can be corrupt, is advised that you use the Cutover because the transfer is from your Exchange On-Prem to Exchange Online and using the PST could have issues like corruption a deltas.

yeah! I do agree with @Nuno Silva !
I've done both successfully but the cut-over is a safer shot
