What is the minimum Exchange 2007 version that will safely migrate Public Folders to Office 365?

We have: Exchange 2007 SP2 RU5 Public Folders and want to migrate them to Office 365

I am aware that this (article) says:
Exchange supports moving your public folders to Office 365 and Exchange Online from the following legacy versions of Exchange Server:
Exchange 2010 SP3 or later
Exchange 2007 SP3 RU10 or later

Question: has anyone recently used Exchange 2007 SP2 RU5 or earlier and not had any problems?
Also... are there any docs that reference this earlier version for a public folder migration?

Thank you for your time in advance!

Why don't you want to upgrade? The minimum requirements are there for a reason. Exchange 2007 SP3 is the minimum you need for any kind of Office365 integration, it doesn't work with older versions because Public Folders are completely different in Office365.
If this was Exchange 2013 (which is what Office365 is based on) the installation would actually fail while you have SP2 in place.

Thank you as always!
Would you recommend SP3 RU10 or a later rollup?

Always the latest. I don't see the point in deploying anything older than the latest.

Simon,

We have a migration batch running for a "cutover migration".
Do you think it will be damaged if we stop it before we upgrade and start it after?

Thank you!
