In one in all my recent articles, we checked out whether or not we must always improve Change 2010 to Change 2016, Workplace 365, or Hosted Change. On this article, we take a unique strategy. Right here we are going to study whether or not you must construct a brand-new Change 2016 or Exchange 2019 server, which suggests you’ll export all of your electronic mail to PST recordsdata and take away your area together with all of your Change servers, or simply do a migration and import the PST recordsdata.
Leaping to conclusions in regards to the double-hop
On the boards, Microsoft and third events, I’m beginning to see a development. IT admins don’t appear to need to spend the time performing new installations of Change or doing double-hop migrations. What’s a double-hop? In case you are operating Change 2010, the very best Change model you possibly can migrate to is Change 2016. You then must take away Change 2010 fully earlier than you possibly can introduce Change 2019. Sure, it is a lot of labor, particularly once you coping with 1000’s of mailboxes. It might take you as a lot as three months emigrate to Change 2016 after which you must do all of it once more to get to Change 2019.
However right here’s a query you must ask your self: Doesn’t exporting mailboxes to PST really take longer? What in regards to the threat of corruption of these PST recordsdata particularly when they’re 100GB or greater? Each choices take up storage, however if you happen to migrate you eliminate the whitespace on the Change 2010 databases. Different questions that come to thoughts are: SLA? Compliance? Danger of information loss?
How do you clarify to your CEO that every one his or her electronic mail is gone since you exported the mail to a PST file and now you can’t entry it? Some may say, properly, there are scripts that mean you can break up the PST recordsdata into smaller ones after which do imports. Sure, Change 2019 has that characteristic the place you possibly can drop the PST file with the identify as the e-mail deal with and it’ll choose it up and import it, however the time it’s going to take to do exports vs. installs remains to be the essential query.
A vote for migrations
I choose migrations for an Change 2010 improve as Change controls the strikes. Sure, you might need corruption within the mailbox and lose a couple of emails however as talked about you get to start out with a clear database. However migrations contain planning, and this consists of:
- NameSpace, new or the identical.
- Newer hardware to host the extra demanding alternate servers.
- SSD disks vs. typical disks.
- Firewall rule upgrades.
- Load balancer upgrades or adjustments. Should you use F5, you will have to make sure you have a legitimate license and assist (and model 15 is now out there with an entire lot extra options). Perhaps you employ Kemp. If that’s the case, you’ll want to plan the adjustments or usher in new ones. Is it cheaper to buy extra VMs or bodily ones?
- Area controller upgrades to assist the newer model.
- Shopper upgrades of Workplace packages.
As you possibly can see, there’s fairly a little bit of planning to be carried out. You probably have distant branches, this makes it a bit extra difficult and prolongs the upgrades as firms typically depart the department workplaces till final and deal with the pinnacle workplace.
Now let’s check out this new strategy. You may spend many hours exporting mail to PST otherwise you simply take the bull by the horns and shut down and delete every part and construct new area controllers with new Change servers. You create all the brand new mailboxes — will be from a script or manually — after which you find yourself utilizing a third-party software program to open the EDB recordsdata and export to PST.
This implies customers coming in may have no entry to the outdated profiles machine-wide. Not solely that, however since you going to create a brand new profile to login to the brand new area, Outlook gained’t be configured.
Change 2010 improve: Keep away from the chaos
All I see is chaos. You might have introduced down the corporate. Overlook about the truth that you’ll want to configure every part on Change and get mail-flow working and URLs setup once more, you’ve locked customers out of every part: printing, accessing outdated data — the record simply grows. Customers who’re configured have clean mailboxes as you’re nonetheless attempting to do exports. They can not work or follow-up on something, the CEO doesn’t know what conferences he has to attend because the account on his telephone not works and he has misplaced his calendar.
Please don’t go this route. There’s simply a lot that may go mistaken. The perfect strategy is to speak to your CAB (change advisory board), advise them that you’ll be doing a number of hops as the corporate desires to maneuver to the newer Change variations and area controllers. Construct a timeline, plan it, talk together with your end-users so that they know what’s going on. In the event that they perceive, it’s going to make it simpler. Sure, they are going to complain in regards to the adjustments, however at the least you aren’t leaving them in the dead of night, not to mention getting your self fired since you need to take the quickest route.
Change migrations are by no means fast, however with the right planning, they are often carried out with out you dropping any recordsdata otherwise you dropping your jobs. Be sure you arrange schedules of what is going to occur and when it’s going to occur so no one’s shocked.
