Questions with a new Lync 2013 install


 I am getting ready to install Lync 2013 and have a couple questions.

Removing and deactivating LCS 2005

I already have LCS 2005 and I plan to remove this before install Lync. I have a front-end server and an Access Proxy setup.  

 I am following the guide here to do this. Do I need to deactivate the LCS proxy and uninstall it first or the front-end server?


Question Regarding Remote Administration Tools

My Lync 2013 server will be running on Server 2012. It tells me that I need to install remote administration tools on the front-end server. My domain and forest level is 2003. This won't affect anything will it?

Certificate Authority

I don't have CA installed on my domain controller. I was just planning on using digicert for my external and internal certificates. Is this possible?

It would be best to clear out LCS cleanly to make sure it's a clean install of Lync 2013

AD functional level of 2003 will be fine, but you could do with a 64bit DC


You can use digicert and definitely if you are planning on any edge services but for the internal stuff you would be best off setting up an internal CA as that will be cheaper and and easier to manage

I don't have a 64 bit DC.
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

You should be ok running the AD prep from the Lync server

I read that if you have a 32bit DC, the AD prep does not work from the installer?

 Also, do I deactivate/uninstall my Proxy/archiving server first?

okay I have uninstalled and deactivated both servers. From reading I am going to manually import the Schema changes using ldifde but I have a question. the example shows the following.

ldifde -i -v -k -s DC1.intranet.domain.com -f ExternalSchema.ldf -c DC=X "DC=contoso,DC=local" -j c:\Schema

I understand the first entry is my schema master DC, but what about DC=X "DC=domain,DC=com

let's say my FQDN is intranet.domain.com. Does that go in the next line?

for the following reason:

I was able to manually update the schema
glad the decommission went ok

sorry chrismas got in the way of the answer to the other

x would be if you had a 3 level domain name i.e.

london.domain.local = DC=London, DC=Domain,DC=Local

if you domain is just domain.local then drop the first DC out
