I have a SharePoint 2013 with lots of SharePoint- and Provider-Hosted apps. This must be migrated to SharePoint 2016. How do i best handle migration of the App-Domain?
Some more information what we do:
- We perform several Test-Migrations and one Big-Bang productive migration
- WebApplication URLs must stay the same. For testing we work with HOSTS-entries on our new SharePoint-Servers and on the Test-Clients. During PROD-Migration, we will change DNS-Entries to SP2016 Farm.
I see two possibilities:
- Also create HOSTS-Entries for every App. As far as i know, i cannot use Wildcard in HOSTS (
- Migrate to a new AppDomain (
*.apps2016.tld). This seems to be a good choice, but i am a little scared things might break during migration when a new AppDomain is in place on the new farm.
Any practical experience is much appreciated.
