How to apply vCenter patches to increase its build level

If there are security fixes which affect your organisation, I would recommend upgrading.

However, I would not upgrade for the safe of upgrading, if it ain't broke, don't fix it!

thanks, I think we have to upgrade it because of the slow SAN communication speed. vmotion in this lower vcenter server is slower than on the other newer one.

how could i find the backend database information for this vCenter server?

vCenter does not connect to your SAN.

Hosts connect to your SAN.

backend database information for this vCenter server?

You mean the SQL database?

I am not sure about what you meant. Since we have two vCenter servers for two different vshpere environments. When we vmotion or storage migrate some vms, we found the speed on the old vcenter is slower than the new one, so we guess it's the vcenter's version problem. Do you think it's the cause of the slowness?  Thanks.

I got the backend sql database from the system DSN tab on vCenter server OS.

My question is since the new installer is the same version as the old one, will it have problem to run if the old version is still on the server?

Please advise.

yes, i made a clone of the vcenter server and also made a full backup of the database.

I will do it tonight, will let you know the result.

thank you, Andrew, have a nice night.

and you.

+1 on the full backup and clone!

do I need stop the vcenter services to backup the database and cloning?

I am afraid the data has been modified inside the databse when I am backuping.

do I need stop the vcenter services to backup the database and cloning?

No, data will change, e.g. performance data, but the configuration will be the same.

If you need to rollback.

I finished the upgrade successfully. It runs smoothly without any problem.

Thank you for help, Andrew, you are the best!

very good solution.
