How to update erpnext from v8 to v11.Kindly give me the update commands

2

Well the commands are simple

bench update

and then

bench update --patch

More can be found here : Bench Commands Cheatsheet

But crucial questions you should answer before updating:

  1. Have you made any changes to any doctypes via the Edit Doctype ?

  2. Have you made any changes to any doctypes via the Customize Form route ? Do you have personalized changes that you want to preserve ?

  3. Have you made changes to the default code in ERPNext / Frappe ?

If your answer to 1 is yes, all those will need to be removed. If no, then all is okay.

If your answer to 2 is yes, then all of them will need to preserved via fixtures which are stored in a custom app.

If your answer to 3 is yes, then you may have to see what can be kept in custom app and what you will have to sacrifice.

I highly recommend you go through the entire process on a spare development server with your current code and database and then think about it on the production.

Perfect. Still try updating first on a development machine.

Before update take backup of database and files like this:

bench backup --with-files

please post job here

hm, I heard that before, but also read often that changes made by Customize Form are creating entries in the database only and therefore no custom app is needed to preserve such changes
