Error message "The dial plan can’t be associated with the Client Access server. Only SIP URI dial plans can be associated with Exchange 2013 Client Access servers".  Do not worry, server will still respond and use this dial plan:

3. Take checkpoint
4. Run ATA_1.6_Update
5. Accept and it will update .NET to 4.6.1 and ask to reboot, go for it.
6. After reboot update will continue.
7. At the end update will propose to launch ATA https://url/configuration
8. Download gateway package, copy ZIP to all gateways
9. Run setup and it will update .NET first
10. As in case of main server after restart setup will continue and will update gateway.

Bad news - two exams combined -  core and voice. Too much of a persistent chat, heavy DRP/HA,

https://support.appliedi.net/kb/a110/how-to-enable-the-disk-cleanup-tool-on-windows-server-2008-r2.aspx

in order to use cleanmgr.exe you’ll need to copy two files that are already present on the server, cleanmgr.exe and cleanmgr.exe.mui. Use the following table to locate the files for your operating system.

 

Operating System	Architecture	File Location
Windows Server 2008 R2	64-bit	C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.1.7600.16385_none_c9392808773cd7da\cleanmgr.exe
Windows Server 2008 R2	64-bit	C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.1.7600.16385_en-us_b9cb6194b257cc63\cleanmgr.exe.mui
Windows Server 2008	64-bit	C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.0.6001.18000_en-us_b9f50b71510436f2\cleanmgr.exe.mui
Windows Server 2008	64-bit	C:\Windows\winsxs\amd64_microsoft-windows-cleanmgr_31bf3856ad364e35_6.0.6001.18000_none_c962d1e515e94269\cleanmgr.exe.mui
Windows Server 2008	32-bit	C:\Windows\winsxs\x86_microsoft-windows-cleanmgr.resources_31bf3856ad364e35_6.0.6001.18000_en-us_5dd66fed98a6c5bc\cleanmgr.exe.mui
Windows Server 2008	32-bit	C:\Windows\winsxs\x86_microsoft-windows-cleanmgr_31bf3856ad364e35_6.0.6001.18000_none_6d4436615d8bd133\cleanmgr.exe

Once you’ve located the files move them to the following locations:

1. Cleanmgr.exe should go in %systemroot%\System32.
2. Cleanmgr.exe.mui should go in %systemroot%\System32\en-US.

You can now launch the Disk cleanup tool by running Cleanmgr.exe from the command prompt.
