Hi all,
I need to upgrading my sandbox enviroment from 7.1 (1611) to 7.2 (1707) and keep all the data and configuration stored in db.
I already successfully updated my dev enviroment but now it's the turn of sandbox enviroment.
Reading https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/migration-upgrade/upgrade-latest-update#scenario-3-upgrade-to-the-latest-application-release I understood that i need to delete and re-deploy the enviroment (Scenario 3, Upgrade your sandbox UAT environment) and I need to do this manually (I haven't the second condition for ask DSE's help).
So I start follow https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/migration-upgrade/upgrade-sandbox-environment but I don't understand the data upgrade in dev env prerequisite and the step "Run data upgrade" after "Import DB", could someone explain it to me?
I know that some relation/index changes from 7.1 to 7.2 so probably I really need to fix it before with data upgrade.
I need to take data upgrade from dev and deploy to sandbox than restore db? I really don't understand.
thanks,
mattia
