I was able to migrate the content of my Umbraco V7 site to V12.3. Currently because i'm not familiar with the Umbraco, i need some hints to determine if the content is migrated successfully. Currently i have completely empty .NET 7 project with Umbraco 12.3 installed, nothing from the code is transferred on this stage. The steps what i followed are these mention in the accepted answer: followed steps Problems what im seeing and trying to resolve are:
- Page Title showing me [object Object]
- Page components are empty and "Add content" button is disabled
Currently im out of ideas.
What data type are you using for your Page Title? Could that be Nested Content? If yes, then make sure that your Nested Content data type setup is correct again after your data migration. You can check your old v7 project to see your Nested Content setup.
Here are some screenshots from one of my projects that I have upgraded to help you.
PS: Things have changed a lot for Nested Content from v7 to v12. The Nested Content is deprecated in Umbraco v11 and it is going to be removed in Umbraco v13. You should consider using Block List or Block grid for future Data Types.
Screenshots from my project:
My Document type that is using a Nested Content data type.
After my upgrade, these document types were missing in my Nested Content setup.
After checking the Permissions and making sure the Is and Element Type is checked for these document types, I could reference them in my Nested Content again and the problem disappeared.
