In my current environment we have SH 2010 RTM, and deployment works fine.
But in the near future there is going to be another farm, and in this one we would like to have it up to date with SP 1, all CUs, hotfixes, etc.
I suppose that developer VMs and its sharepoint versions, should match the versions otherwise SharePoint wont allow to deploy the WSPs. Is that correct?
So I suppose I have 2 options: 1. Leave the new farm in RTM 2. Upgrade the current FARM to SP1, and June 2012 CU. (do the same with developer VMs)
