Rename a Skype for Business Server (Front end or others)


 The procedure is explained in simple step's. I had this a couple of times, not only why a customer wanted to change the name. Its the same if you made a typo ;)

 Today a came across with an double task to do. Upgrading a SBS from Lync 2013 to Skype for Business. This ahs put me into a dilemma of the chicken egg problem.
Should I do an in-place upgrade first or a rename or or or?
The answer to me was straight forward. Since the servers to be reinstalled, I decided removing the SBA entirely and do a re-deployment with SfB. Since it was an SBS, equal with an Front End server, please make sure there are no user hosted or anything else.

Renaming Process:

  1. Remove Skype for Business server from topology
  2. Publish topology.
  3. Run Skype for Business Server Deployment Wizard local setup on server to remove Lync components (or run the bootstrapper)
  4. Uninstall SQL Server. Front-ends have LyncLocal and RTCLocal instances. Remove both, rebooting between instance removal.  Edge only has RTCLocal instance. 
  5. Remove SQL Server 2012 Management Objects (x64)
  6. Remove SQL Server 2012 Native Client (x64)
  7. Remove Microsoft System CLR Types for SQL Server 2012 (x64)
  8. Remove Microsoft Skype for Business Server 2015, Front End Server
  9. Remove Microsoft Skype for Business Server 2015, Core Components
  10. Delete leftover data:
    Delete C:\Program Files\Microsoft SQL Server
    Delete C:\Program Files\Microsoft Skype for Business Server 2015
    Delete C:\CSData
  11. Rename server and restart
  12. Wait until AD replication completes with new server name.
  13. Open Topology Builder, add a new server to existing pool and publish. (If this is a SBA or Standard Edition Server, the pool and the server FQDN is identical.)
  14. Reinstall Skype for Business Server 2015components and all cumulative updates
  15. Generate new certificate with updated server name and assign to appropriate services using Skype for Business Server 2015 Deployment Wizard.
  16. Restart all servers in pool at same time (only relevant for front-end servers in an Enterprise pool).



Note and Warnings:
Careful if this is the Pool where CMS is located. There you need to migrate the CMS to another pool first and starte the rename procedure. than you can move back the CMS.
Same to users or other applications. simply move them to a different server and move back after the rename procedure has finished.

Note:
This procedure applies to Lync server too.

How to hide users from GAL if they are AD Connect synchronized

How to hide and un-hide users from Global Address List (GAL) in Exchange Online if they are AD Connect synchronized Hiding User from GAL isn't possible if those are synchronized form On-Premises Active Directory. The local AD is the leading system for all important attributes, like SMTP, UPN and hiding from GAL. Especially during a cross-tenant migration, you do not want to see not migrated user in the GAL. Those User aren't actively working until their cut-over day. Since the Exchange Online attribute  msExchHideFromAddressList s is an AD on-premises parameter, we have two possible ways hiding user in BME from GAL.   Modify the AD Connect for your teant with a custom rule, by using a extensionAttribute to set the HidefromGAL. In this rule, for users which have an entry in the extensionAttribute, hiding / un-hiding will be controlled by AD Connect This is the best option for Cross-Tenant Migration, if you run 2 or more AD Connect system We direct modify the AD hide at

Lync Edge Server FQDN and IP PORTS (Version 1.2, Update 26.11.2014) As we all know, we can configure Lync Edge Server in several way. 1) Single Edge Server with a SINGLE IP ADDRESS 2) Single Edge Server with MULTIPLE IP ADDRESSES (3x IPs) 3) Multiple Edge Server in a Pool, with MULTIPLE IP ADDRESSES (Zx 3 IPs) Regardless what we are going to configure, there are common / well-known TCP Port necessary making Lync work, which are: Access: Port: 443 and 5061 Conferencing: Port: 443 and (444) AV: Port: 443 (I have not listed other ports, e.g. STUN or the dynamic port range. This is not required for the topic discussed here) External FQDN with single IP address: What can we see here? If we are going to choose a single IP address, we would have TCP Port overlapping. Therefore the only way avoiding this is assigning other ports. Additionally we will also see and are reminded that Lync highly depends on DNS. If we have single IP, we must have use single, unique FQDN fo
