Skype for Business SBA Migration Cheat Sheet

Okay, I’m supposed to be publishing my LPE article. But its not done yet. So have this “Quick and Nasty” guide instead

I’ve recently been migrating customers from older SBA’s running Lync 2013 code to newer SSD based SBA’s running Skype for Business 2015 and as such I’ve been working on a tool for Pool migrations but its not quite there yet.

Till then, I use this Cheat Sheet to make the migrations quick and easy and I encourage you to as well.

In summary, to migrate users from one SBA to the other, they have to go through a FrontEnd. You also need to migrate the Analog Devices, Meeting Rooms, Common Area phones and update a few attributes.

• New DNS Names
  • First off, create new DNS names for everything, including the gateways, as you need to get everything off the old SBA before you can decommission it
  • If your re-using any hardware tht your changing the DNS name on (analog gateways for example) you will need to update its certificate as part of the migration
• Update and Publish Topology with new SBA’s and gateways
  • Do not rename the trunk for any gateways/ata’s hosting analog devices (More info on Greig’s site here)
  • Don’t forget to create trunks between any FrontEnds and the SBC if your doing that.
• Follow your vendors instructions for building a new SBA/GW
• Update or Create new Voice Policies
  • Create new routes between the new SBA and new Gateways
  • Update the voice Policies to allow the new routes
• Export the endpoint lists out of the current SBA so we can track them for later

Get-CsAnalogDevice -Filter {RegistrarPool -eq "oldsba.skype4badmin.com"} | export-csv c:\Skype4badmin.com\migration\OldSba-Analog.csv
Get-CsMeetingRoom -Filter {RegistrarPool -eq "oldsba.skype4badmin.com"} | export-csv c:\Skype4badmin.com\migration\OldSba-Meeting.csv
Get-CsUser -Filter {RegistrarPool -eq "oldsba.skype4badmin.com"} | export-csv c:\Skype4badmin.com\migration\OldSba-Users.csv
Get-CsCommonAreaPhone -Filter {RegistrarPool -eq "oldsba.skype4badmin.com"} | export-csv c:\Skype4badmin.com\migration\OldSba-Common.csv

• Re-Home Everything on the temp FrontEnd

Import-csv c:\skype4badmin.com\migration\OldSba-Users.csv | Move-CsUser -Target TempFE.Skype4badmin.com
Import-csv c:\skype4badmin.com\migration\OldSba-Analog.csv | Move-CsAnalogDevice -Target TempFE.Skype4badmin.com
Import-csv c:\skype4badmin.com\migration\OldSba-Common.csv | Move-CsCommonAreaPhone -Target TempFE.Skype4badmin.com
Import-csv c:\skype4badmin.com\migration\OldSba-Meeting.csv | Move-CsMeetingRoom -Target TempFE.Skype4badmin.com

• Update the Analog Gateway attribute on the Analog Devices
  • If you have multiple Analog Gateways associated with the SBA, Rinse and repeat

Get-CsAnalogDevice -filter {Gateway -eq "OldAnalogGW1.Skype4BAdmin.com"} | Set-CsAnalogDevice -Gateway "NewAnalogGW1.Skype4BAdmin.com"
Get-CsAnalogDevice -filter {Gateway -eq "OldAnalogGW2.Skype4BAdmin.com"} | Set-CsAnalogDevice -Gateway "NewAnalogGW2.Skype4BAdmin.com"
Get-CsAnalogDevice -filter {Gateway -eq "OldAnalogGW3.Skype4BAdmin.com"} | Set-CsAnalogDevice -Gateway "NewAnalogGW3.Skype4BAdmin.com"
...
Get-CsAnalogDevice -filter {Gateway -eq "OldAnalogGW9.Skype4BAdmin.com"} | Set-CsAnalogDevice -Gateway "NewAnalogGW9.Skype4BAdmin.com"

• Wait for AD replication and repeat the process from FE to New SBA
  • Enjoy a Coffee whilst you wait

Import-csv c:\skype4badmin.com\migration\OldSba-Users.csv | Move-CsUser -Target NewSba.Skype4badmin.com
Import-csv c:\skype4badmin.com\migration\OldSba-Analog.csv | Move-CsAnalogDevice -Target NewSba.Skype4badmin.com
Import-csv c:\skype4badmin.com\migration\OldSba-Common.csv | Move-CsCommonAreaPhone -Target NewSba.Skype4badmin.com
Import-csv c:\skype4badmin.com\migration\OldSba-Meeting.csv | Move-CsMeetingRoom -Target NewSba.Skype4badmin.com

• If you created new Voice Policies for the endpoints on the SBA, update as appropriate

Import-csv c:\skype4badmin.com\migration\OldSba-Users.csv  | Grant-CsVoicePolicy -PolicyName "AU NEWSBA International"
Import-csv c:\skype4badmin.com\migration\OldSba-Analog.csv  | Grant-CsVoicePolicy -PolicyName "AU NEWSBA International"
Import-csv c:\skype4badmin.com\migration\OldSba-Common.csv  | Grant-CsVoicePolicy -PolicyName "AU NEWSBA International"
Import-csv c:\skype4badmin.com\migration\OldSba-Meeting.csv  | Grant-CsVoicePolicy -PolicyName "AU NEWSBA International"

• Wait for AD replication again
• Update the Routing on your Analog Gateways and SBC’s the point to the new SBA
• Run through your test plan
• Remove the old Gateways and SBA from the topology

Hope this helps.

Update: One of my followers on Twitter @ricsip82 mentioned you can have ExchangeUmContacts hosted on the SBA

To check for this simply run the following powershell, if anything is returned, just migrate them with Move-CsExUmContact

Get-CsExUmContact -filter {registrarpool -eq "oldsba.skype4badmin.com" }
