[V7] Migration Error from V6

Got little curious and wanted to migrate from V6 to V7. And it seems problematic

http://pastebin.com/zL5zUQFA

Below is the command I executed before

mysql -u root -pdkkdfdkfdkfj 1bd3e0294d < 20160718_77722540_database.sql
bench remove-from-installed-apps mandrill_integration
bench remove-from-installed-apps sendgrid_integration
bench remove-from-installed-apps frappe_subscription
bench migrate

Thanks,
Amruth

Hi,

I am also encountering similar problem. Please see my error message below.
I switched to developer mode and I was forced to do upgrade to v7. Migrate throws the error.

$bench switch-to-develop --upgrade

Thanks.

after doing some comparison between V6 and V7, a straight forward migration cannot be done from V6 to V7 as no of database rows are completely different. I think switch for v6 to v7 script has to be written to perform this.

Below is the comparison of the two V6 has 263 rows with V7 has 306 rows. Default mysql dump wont work. Table export is what I think would work.

Hi, do you want to change to the develop branch or upgrade to ERPNext 7. The tables are different, but when you run bench update --upgrade from ERPNext 6 there will be “patches” that will be run to make sure the database is in the state ERPNext 7 wants it to be in.
