We have LYNC 2013 Enterprise Pool collocated with LYCN 2010 Enterprise Pool. CMS database is on LYNC 2010. I am planning to apply February 2015 CU patches on both LYNC pools and found great blog from Iain Smith on how to apply DB patches in coexisting environment.

(https://northernlync.wordpress.com/2013/06/17/lync-2010-and-lync-2013-coexistence-environment-cu-patching/)

When I executed DBupdate command on LYNC 2010 on LYNC 2010 Frontend Pool server in my test environment, I got the below error message and continued to update other databases and finished with Success on all other databases.

Here is my concern, can I ignore the error message?

Or, shall I use the below command

Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn DBServer.domain.com   -ExcludeCollocatedStores

( NOTE: There is no -UseDefaultsqlpaths parameter in the above command....)

(The parameter ExcludeCollocatedStores suppresses a warning message telling you that any collocated database stores must be installed on the local computer. If your lync FE databases are collocated with Archiving or Moinitoring database, you will get a warning message. You can use ExcludeCollocatedStores to suppress it.

But the Install-CsDatabase still work successfully without parameter ExcludeCollocatedStores. )

Shall I run the first script on dababase server instead of FrontEnd server?

Please suggest me the best way to update in production.

Thanks in adva

Hi,

Base on my understanding, if this is an  Enterprise Edition Back End Server and there are collocated databases on this server, then you need to type the command line:

Install-CsDatabase -Update -ConfiguredDatabases -SqlServerFqdn <SQL Server FQDN>  -ExcludeCollocatedStores

Thank You Eason,

Can I ignore -UseDefaultsqlpaths parameter ?
