I am using v11 since more than a year now and would like to upgrade to v12 ,
i have many custom docs and huge data (of 1 year) , My challenge is how do i now upgrade to v12 keeping custom doc types and data intact.
I am not familiar with bench so if you could tell me where the DB would be available in existing installation and how do i add it to new installation ?
Also , I created doc type using custom doc types so hope that works !!
