Moving from O365 E3 to Business Premium

Since the Office version will change from Business to ProPlus we would need to reinstall the office software on the workstations
I would plan on removing and reinstalling it with the click to run using the business premium license option, but you should be able to just update the license. I ran into some systems, that didn't want to fully convert from ProPlus to BP when the user logged in after the licensing change. Normally, the user would be notified that they need to close out of the Office suite and it would automatically update the system to the new licensing version. This was about a year and a half ago, so it could be smoother. You can always test it to see what happens.

The mailboxes and their email will migrate automatically (after some minutes of panic where you can't see any mailbox during the migration)
I have switched some mailboxes from BP to E1 and vice versa and haven't really noticed anything. It is not with active users, so I can't say for sure. Test it out, but still do it after hours.
It only takes a license change, the mailbox will continue to be available. Just a licensing change.

Also Office 365 Business Premium supports Exchange in Hybrid Mode as well

I would hate to have to manage O365 and an on-premise Exchange server. Any plans to decommission that on-premise Exchange server? To relay LAN devices, we setup a Windows IIS server to relay the copiers, Veeam, notification emails. You create a mail flow connector in the O365 Exchange admin center to your Windows IIS box. We used Skykick when we migrated to O365, so all the email on the on-premises Exchange was migrated into the O365 accounts. I could not wait to get rid of our on-premises Exchange box after migration to O365. I’m sure you don’t want that thing anymore either.

I've activated a Business Premium trial license on my account and deactivated the E3 license, everything looks good so far
The only strange thing is this, I suppose I just have to wait
UPDATE: I've manually removed the old subscription with the script "$Env:Programfiles\Microsoft Office\Office16\OSPP.VBS". Everything still looks good so far

You had to do that manually? Ugh.

@travisdh1 well it would remove itself automatically eventually, but looks like it could take hours or even days to sync, reading on other forums

It looks like you don't need to uninstall and reinstall Office

Correct
