[Release] ERPNext Version 12

I attempted to upgrade v10 to v12 and after facing several issues which i resolved, i landed in v11.1.4. All attempts to move to v12 since then have failed following the same steps outlined in all posts made about migration to v12 so far.

I have the same problem. It is the patch erpnext.patches.v12_0.set_priority_for_support
A quick workaround is to disable this patch if you don’t ever use support doctype.
Proper solution is not known to me.

This fails in case you have custom apps. Would suggest changing the instructions to:

Switching to Version 12

$ bench update
$ bench switch-to-branch version-12 frappe erpnext --upgrade

Switching to Version 11

$ bench update
$ bench switch-to-branch version-11 frappe erpnext --upgrade

Finally installed v12, restored v11 backup (with custom apps), and then updated to v12 successfully. Below are the steps i followed:

// installed erpnext v12 (using install.py)

//restored from v11 backup

switched to 11
dropped site
created new-site
turned on developer mode
installed erpnext on the site
switched to 11
dropped db
restored db
fetched the custom apps
migrated
restarted bench
reloaded nginx
update bench
change admin pwd

//updated to v12

switched to 12
ran bench run-patch erpnext.patches.v12_0.make_item_manufacturer
switched to 12
restarted bench

@Vinob_chander_Ramasw , Thats a feat, restoring to v12 from previous database backups. Please share a detailed document, with clear steps for the mutual benefit of the community.

I’ve restored several v11 backups to a fresh v12 instance following the standard procedures without much issues. The trouble is restoring v10 backup to v12. As of right now, it’s near impossible as far as I can tell as there are too many patches required which don’t come standard with the restore process.

one option would be to restore ur v10 backup on a v10 instance created from a snapshot (if you already have a server with v10), update to v11 and then to v12

trying to migrate a system I got this: frappe.exceptions.CharacterLengthExceededError: DocField, Row 11: ‘Depends On’ (eval:([“Data”, “Select”, “Table”, “Text”, “Text Editor”, “Link”, “Small Text”, “Long Text”, “Read Only”, “Heading”, “Dynamic Link”].indexOf(doc.fieldtype) !== -1)) will get truncated, as max characters allowed is 140
I could not find much about. Any ideas, please!
