How to upgrade from old version of netbox

[johnarvi...@gmail.com]

Hello,

I have tried a bit but wanted to ask the mailing list on what would be a good way to upgrade a old version of netbox (1.9.5) to the newest version (2.1.2).

I tried to simply download the newest release and run upgrade.sh but this ended in a "AttributeError: 'module' object has no attribute 'SSL_ST_INIT'"

Then I tried (after a snapshot restore of my vm) to upgrade to 1.9.6, but this ended in a Internal Server Error.

How should I proceed? I don't like that every time I need to upgrade I get stuck troubleshooting.

Other than that netbox is a great tool! Love the job that is being done.

Tried to add pyOpenSSL==16.2.0 
to requirements.txt but then I got 

Collecting static files (python netbox/manage.py collectstatic --no-input)...

Traceback (most recent call last):

Would it be easier to have a backup of the db, start a new netbox install and import?

This file does not exist in the current code base. Did you just copy the new code on top of the old code? The old code needs to be completely removed. The recommended practice for packaged upgrades is to switch to a new directory for each upgrade and use a symlink. For instance:

$ ls /opt

netbox -> netbox-2.1.2

netbox-2.1.1

netbox-2.1.2

Aside: another way that works is to use a git checkout, and inside the checkout select the version you want (this gives you a "detached" working copy, not connected to any local branch)

git fetch

git tag   # to list available versions

git checkout v2.1.2

./upgrade.sh

supervisorctl restart netbox

When a new version comes out, just repeat.  The 'git checkout' will automatically remove files which were in the previous version but not in the current.

That is correct, I used an old way of upgrading netbox.

I looked at the link you refereed but something does not make sense:

# ln -sf netbox-X.Y.Z/ netbox

In my case this create a symlink in the folder netbox to the folder netbox-X.Y.Z/

# cp /opt/netbox-X.Y.Z/netbox/netbox/configuration.py /opt/netbox/netbox/netbox/configuration.py

This tried to copy a non existing file and overwrite my existing config

Same with the rest of the cp in the documentation

Thank you for your response, I managed to successfully upgrade with these commands. (May be because of old git commands I have ran)

cd /opt/

git fetch

git checkput v2.1.2 -f

./upgrade.sh

supervisorctl restart netbox
