Future-proofing your Microsoft Exchange Upgrade & Migration Strategy
However the last migration or upgrade you performed was probably a little easier; the requirements were different then, and there was dramatically less data than today. The move from Exchange 2003 to 2007 was mostly about the new 64 bit hardware required, but the move to Exchange 2010 is often about the volume of data instead.
The future... if we actually had an endless supply of dilithium crystals or flux capacitors, gadgets like floating skateboards and Tricoders might be more common. But sadly they're not; so the only real prediction I can make for the future (that's relevant to this blog post anyway) is that Microsoft are planning to release a new version of their Exchange Server software every three years. We should be seeing the next version towards the end of next year, currently being called Exchange 15.
Like Christmas, it feels like new versions of core server software come round far too quickly, especially such valuable services like Microsoft Exchange. We've previously mentioned the lengthy procurement cycles that keep such services a constant version behind before, which generated some good feedback and discussion; many Exchange admins told me those delays adversely impact their own deployment plans, which is intensely frustrating for them and often forces their migration project into the red.
So, rather than roll out the ubiquitous predictions for 2012; I'm going to suggest that in the absence of 1.21 Gigawatts you can take a stab at future-proofing your Exchange environment now, so you're not left thinking in future -
"I'm migrating again. Surely not? Didn't I just finish the last upgrade?"
As your users make merry with the disk space allocated to the Exchange Stores, their mailboxes have grown and grown, you're probably wondering how you're going to move several Terabytes of data to the new Exchange platform; but, more importantly wondering when you might have to do this again. The short-term nature of IT and the constant cycle of upgrades and migrations means you may have to answer those question sooner than you expected.
One simple solution that future-proofs your migration and upgrade strategy is to deal with the data now by augmenting your on-premise Exchange with a Cloud based email management solution. Using this Cloud based email management solution is simple; the elastic and scalable nature of the Cloud lets you 'dump' your oversize email stores into a secure, scalable, flexible and resilient solution that will grow with you, but at the same time allow the users to have direct access to that email data through Outlook as though it was still on Exchange.
Now here's the part of plan we don't talk about very much, but one that provides a great degree of flexibility. When the next migration or upgrade comes around, or if you want to move from one platform to another, having already dealt with the data means your core email service i.e. Exchange, can be anywhere or anything. Upgrade, downgrade, move to Office 365 and back again, migrate some users or all users, the choice is yours; Augmenting Exchange with the cloud means you're not tied to any one solution or version, both today and next year when it's time to upgrade again.
