According to Salesforce Winter '18 Sandbox Preview Instructions
Each sandbox created after Sep 8 and before Production new release (middle of Oct) will become Summer 17, while created before Sep 8 - Winter 18.
We are trying to perform profiles backup by deploying them from Winter 18 Sandbox to Summer 17 sandbox environment. We have pulled all settings: object access, class access, layout assignments.
But in Winter 18 Salesforce has added new metadata:
<field>Asset.StockKeepingUnit</field> <layout>Scorecard-Scorecard Layout</layout> <userPermissions>..<name>ListEmailSend</name></userPermissions>
Given examples dont exist in Summer 17. Each validation returns one error and takes about 15 minutes to be complete.
If there any easiest way to deploy profiles to downgraded version?
