My company is a Salesforce ISV partner. We have a dev org that we package up and then push upgrades out to our customers as needed. I realized that this weekend some of our customers will be upgraded to Winter 16, but our dev org will not be upgrade until next week. If I need to make a fix in our dev org next week and push out that change to those upgraded customers, will that be possible? Basically, can I install a Summer '15 managed package to a Winter '16 ORG?
I know this information is out there, somewhere, but I'm just unable to find it today.
