install exchange 2013 alongside 2010 for testing without impacting production 2010

im running exchange 2010 sp3
I have installed 2 x 2013 boxes running all roles
I have created a dag
I want to test 2013 before I start moving mailboxes
im at the stage where I need to configure these with my kemp Load balancers and set the urls
how can I setup this without impacting my main production 2010 exchange
can I just setup different urls and dns names then when happy change them to the urls that 2010 exchange is using

It would depend on what testing you are waning to do - are you wanting to test connectivity? Dag failover?

If you've installed the exchange servers into your existing domain they should have already integrated into your network and exchange organisation. Ideally for testing you should have set them up on a completely separate network/system.

You should be able to set it up using different url's for the moment and then switch it over but just be careful regarding autodiscover - if you change that it could start causing all client systems to connect to the exchange 2013 server instead of the 2010 while you're testing it.

how best should I approach autodiscover?

or can I set all exchange 2010 & 2013 urls to use the same
and it will only affect users that I move to 2013
Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

The main thing isn't setting the url's, it's the changes to the dns records so systems point to the servers. Once you change those records all systems will start connecting to the Exchange 2013 server, regardless of where the mailbox is located. If Exchange has been setup correctly this should still work fine as 2013 will just proxy to 2010 but if you start installing updates, rebooting, etc it will affect users.

You could setup dns records locally on your machine's host file to point autodiscover, owa, etc to the exchange 2013 server for testing. This can only be done internally but will allow you to test it without affecting everyone else.

have you any experience with kemp load balancers?

Hi Doug

No unfortunately haven't had any experience with them at all. Haven't done a lot with hardware load balancers personally.
