vCenter Update (DB is mirrored & SSL questions)

Hi,

vCenter is currently 5.1.0a and I will be upgrading to 5.1 Update 1b.

2 Questions if I may:

• The vCenter DB is part of a SQL mirrored setup.  Prior to upgrading is it recommended that I break that mirror and then re-establish when I am done, or should that not make any difference?

• Is the built in SSL certificate changed during the upgrade from 5.1.0a to 5.1 Update 1b?  We do not use our own but this is for a Citrix XenDesktop VDI environment where the current SSL certs have been exported from vCenter and imported to the DDC servers and I would like to know if I will have to do that again or if the same SSL cert will be used after the upgrade.

Thanks
