hi
I suggest you create a 7.x template project and compare the code.

I have a solution based on ABP 3.1 and now I am trying to upgrade it using the abp update command.
The Update command is throwing an error.

hi
MyGet is down now. You can try again after it is back. You can also upgrade packages to the latest manually.
https://myget.org/
For this kind of upgrade across multiple versions, the update command is not enough, and a lot of manual work is required
