Moving away from SBS 2008...

As the end of life is rapidly approaching, I'm considering ditching my 2008 SBS & moving on to bigger & better things.
Any suggestions on moving to Exchange 2013 or 2016 vs Office 365 & an exchange hosted plan?
Will I have issues taking the currect 20085 SBS out of domain & 'replacing' with an exchange server?
It sounded like a good idea at the time, but I really don't use any of the other features that SBS comes with.

Office 365 email is NOT the same as Hosted Exchange.

Office 365's email uptime is rated at 99.9%, which means your email could be down for approximately 9 hours per year. For small businesses with a few employees, that may be fine. But for SMBs it's not acceptable.

Hosted Exchange's email uptime, however, is far more reliable - 99.999% comes out to just 5.5 *minutes* in one year.

I'm about to migrate my entire office from an in-house Exchange 2010 server to Hosted Exchange.

As far as migrating from SBS Exchange or any version of Exchange - this process is well documented and supported by Microsoft. It may involve first updating some rollup or Service Pack updates, and it could be tedious, but certainly doable.

As for your Windows Server - if you're in an active directory network, Windows 2012 Essentials is a great solution. Or better yet - rumor has it that in about 1 month, Microsoft will be releasing Windows 2016 Server.

If you do not have a domain in your office, you could opt to replace SBS with a NAS device, if all you really need is a file server.

I'd love to hear what ecarbone considers "Hosted Exchange" to be - and what service is guaranteeing a 99.999 uptime.

There is no such thing as 100% uptime 100% of the time.  you need to consider what is acceptable to you.  Then weigh the costs.  Whatever e-mail services you employ will be subject to your ISP, the Exchange provider's ISPs, maintenance windows, Microsoft's ability to flawlessly patch things, etc.  I find it silly to expect ANY Exchange provider to RELIABLY provide five-nines uptime for exchange.

Here is a link for your pleasure:

And I never said anything about 100% up-time.
I was comparing 99.99 to 99.999

Thank you for clarifying which "hosted exchange" product you were referring to - If you did a simple google you got many different results. For my google results, intermedia is the 4th listed... so it was far from clear.

As for high availability, thanks... I'm well aware of the concept.

and no you didn't say anything about 100% my point was in the rest of the comment:
"you need to consider what is acceptable to you.  Then weigh the costs.  Whatever e-mail services you employ will be subject to your ISP, the Exchange provider's ISPs, maintenance windows, Microsoft's ability to flawlessly patch things, etc.  I find it silly to expect ANY Exchange provider to RELIABLY provide five-nines uptime for exchange."  

According to the EE article you linked to, the following will affect the applicability of Microsoft's Three-nines availability:
-      ‘Due to factors outside Microsoft’s reasonable control’
-      ‘Resulted from Customer’s or third party hardware or software’
-      ‘Resulted from actions or inactions of customers or third parties’
-      ‘Caused by Customer’s use of Service after Microsoft advised to modify its use of the Service, if -      During scheduled downtime
-      ‘During beta and trial services (as determined by Microsoft)’
Some of these may not apply, but you can sure some do.

Further, intermedia's offering does NOT include Microsoft Office which all but the basic plans do.

Odds are, your outages on three-nines or five-nines will be far more than 9 hours per year when you factor in all other possibilities.

And the guarantee is backed financially - I couldn't find the "or else" part of intermedia, but odds are it's not a 25% refund of service fees as it is with Microsoft.  Most SLAs I've seen are daily percentages.

Look, I'm not saying you should or should not go with Hosted Exchange (and Hosted Exchange and Office 365 ARE the same thing when it comes to Exchange - the differences are in the details and what the provider offers as an SLA)  Ultimately you (especially gromack since this is his question) needs to weigh the pros and cons of all services you want to consider.  A big pro of Office 365 is that it includes OFFICE! (in most SKUs), but SLA is a consideration - and HOW the SLA will be honored is also a consideration - as well as support.
