Cheers for the info.

I shall let the installer continue with the upgrade process, and then check the DSN details.

@Home I forgot to update my DSN before the upgrade and updated my vSPhere setup without any problems. Afterwards I removed the 32 bit DSN and replaced it with a 64 bit DSN. No problem.

Hi

Looking at upgrading vCenter 4.0 update 1 to vCenter 4.1 and have a DSN question.

The 4.1 upgrade guide says it needs a 64bit DSN, whilst the previous versions used a 32bit DSN.

I created an additional 64bit DSN to point to the vCenter DB - the aiming being to get the installer to use this.

When I run the 4.1 installation it reports I have an earlier version of vCenter alredy installed and it will upgrade this version.In the database options window it detects the 32bit DSN - so I cannot specify the 64bit DSN I created earlier. The next window has the upgrade options for the database, however I'm reluctant to continue on as it's using the 32bit DSN.

Any advice?

@donkarnash I had the same problem as you by the sound of it. I wrote up a workaround here:
