How to get the ERPNEXT digital ocean to the VM

ERPNext
1

Hi all,
I have the ERPNext in the digital ocean with customised most of the ERPNext codes from masters and added additional doctypes as per the client convenience. Now they are expecting this whole ERP in VM as there is insufficient net facility in their places. Any way to migrate this to VM. As there is no facility to covert the files to OVA format in digital ocean. I have tried to pull the folders and set the bench migrate it shows pkg resource file error. Any way to get the Fully finished ERP in to VM. with all set data’s and codes.

Unfortunately it doesn’t seem like DigitalOcean has a feature to do that.

For the code changes, you can just use any Git hosting service like GitHub or BitBucket (They have private repositories) if you haven’t done that yet.

For the data, you can use bench backup --with-files and copy the backup file over to the new VM

So basically:
You setup bench again on the new system, make sure it’s a clean VM.
Create a new site by bench new-site [site-name]
Do bench get-app erpnext [git-repo-url]
And then follow the instructions here : Restoring From ERPNext Backup · frappe/erpnext Wiki · GitHub

Hi @vjFaLk Thanks for your reply,
I will work on it and revert back.

Even for ERPNEXT code edit also the migration will work?.

As I said for the actual code changes you’ve made, you want to push it to Github / Bitbucket and then use bench get-app. The backup command will not take a backup of the code.

Hi @vjFaLk I have followed these steps and got the app
But in erp screen it doesn’t reflecting any thing. I have given few questions below.
while creating the new site the db pulled from the github is showing in the mysql -u root -p. and db is not showing in the bench mysql,
While giving the bench migrate option it show the error after restoring the db.

How can i move this to my bench mysql.

It seems that you’re on an older version of ERPNext and Frappe and what’s happening is that it’s creating issues because of version and code differences.

Now, there are multiple ways we can handle this.

  1. The dirty way. You can create an image out of your DO Droplet for using in a Virtual Machine. Which is not very reliable : Refer to this. If you can make it work, it’ll work, but in the long term you might face issues.

  2. The clean way : If you have separate DocTypes that add to ERPNext, you should create a separate app for them. If you have any ERPNext related code changes, you should stash them (If you haven’t committed them). Basically, separate your code from ERPNext / Frappe code and then run bench update to get everything to the latest version and reapply your code changes. Once you do that do the backup and restore process again. (Make sure you start with a new VM as well)

  3. Another hacky thing you can try is replacing the frappe folder and it’s contents on your VM with the frappe folder on your VPS and then try to migrate on a new site. But I doubt that would help either.

Any Way to roll back my VM ERPNext to older version.

I am Using this version of erpnext in digital ocean.

8

Another thing you can try is : Get a fresh VM, run the production setup and try replacing the entire frappe-bench folder on your VM with the frappe-bench folder from your Droplet.

Unfortunately, here is no clean way to do this.

Yeah i have done this already Thanks
