Lync 2013 CU3 Install-csdatabase processing has competed with warning

Hello!

I have tried to update my lab environment to CU3 (october 2013) and get the strange warning while running install-csdatabase comand:

****Creating DbSetupInstance for 'Microsoft.Rtc.Common.Data.AbsDatabase'****
Trying to connect to Sql Server vm-labexch-sql.labexch.ru. using windows authent

.labexch.ru-[2013_11_18][19_06_46].log"
VERBOSE: Installing "ApplicationStore" on vm-labexch-sql.labexch.ru,collocated: False

After applying this database update all services have started successfully, and everything seems to work fine.
As I understand, installer could not execute SQL batch file RtcAbTypes.sql.
Can I safely ignore this warning and try to upgrade my production? Or it may cause problems?

Any help would be appreciated.

Best regards, Pavel
