We are working on to upgrade/migrate a application from 7.2 to 8.2 version using express migration tool 2.0. Database is in SQL Server 2012. While migrating, app data folder to the tune of 3 GB is created in destination website folder. Does this correct or we need to rerun the tool. Also can we delete this APPDATA folder while taking this to Final production deployment. Without APPDATA folder the total size of website folder is 700 MB.
Any suggestions...
