Office 365 - Archive Migration

Hi guys,

We are about to migrate to Office 365 E3 plan from Exchange 2010 but the challenge we face in migrating on-premises Archive having around 2TB space and is very important and critical for and must be available to users all the time.

How to move 2 TB archive data> What are the options Microsoft is giving for current archive for cutover migration? Are there any good third party tools available in market?

2TB is a lot of data. It will probably take weeks to upload. In my experience, no matter what your internet speed, Microsoft seem to throttle the upload speed.
Does the archive really need to go on O365? Another option would be to store the archive in PST files on the user's local PC's or on a local server/NAS.
Maybe upload the last few months of email to O365 so it is accessible on mobile devices, etc and store the rest locally.
How many users do you have?

We have around 60-70 users Archive enabled and as I said data are important.

Archives are not migrated during Cutover migration. You will have to either separately upload them via the PST Capture or some 3rd party tools, or use the new PST import process that allows you to send the data directly to Microsoft on a physical drive: https://technet.microsoft.com/en-us/library/ms.o365.cc.ingestionhelp.aspx
