hello i recently began to develop apps for sharepoint 2013 online on my office365 account. And i am getting more familiar with upgrade process. So I know how to upgrade app for sharepoint online. Only thing is to change version in manifest to higher version. But my problem is that when i attach database to project(as dacpac file) then upgrade fails and generates error ' The content database on the server is temporarily unavailable.
Details: 0x80070002 ' I always get this error. When i deploy app first time with database then everything is ok. But when want to upgrade database then i got this error. I can add that app is autohosted Any ideas what causes errors? Best regards.
