Mixed ESXi hosts in cluster?

[wframe]

Hi all,

Currently running a cluster of 4 hosts with ESXi 4.1.0 build 260247.  Have two new hosts I would like to add to this cluster.  From what I can tell, running ESXi 4.1.0 build 348481 on these hosts should not be a problem.  This would last less than a day or two as the old hosts will be upgraded to the same version/build of ESXi as time permits.  Has anyone run into a similar situation with adverse results?

Your insight would be greatly appreciated!

Regards,

W

No problem with this scenario. Go ahead.

Only check if your vcenter supports both versions.If necessary, upgrade your vcenter first. http://partnerweb.vmware.com/comp_guide/sim/interop_matrix.php
