Upgrading from 0.7.3 to 0.8.2 / 0.9.0

[nuchin]

Hello,

I am attempting a test to upgrade from 0.7.3 to 0.8.2, however, whenever I visit my categories page, the app throws an error like below:

error: TypeError: Cannot read property 'cid' of null
at async.waterfall.category.children (/home/ubuntu/nodebb-0.8/src/categories.js:330:43)

I'm able to actually upgrade from 0.7.3 to 0.9.0 with none of these errors. What should I do, without losing my categories and all their posts?

I am assuming you are getting this error on 0.7.3 or 0.8.2 cuz that stack trace doesn't point to the correct place in 0.9.0, I suggest making a backup and upgrading to 0.9.0 and check if everything is working.

@nuchin What steps did you follow to upgrade from 0.7.3 to 0.8.2?

Which theme are you using and the version of that theme?

[nuchin]

I've already tried to go straight from 0.7.3 -> 0.9.0 with success. Plugin support hasn't caught up yet though.

@pichalite , I'm using a 2nd instance of nodebb, with a 2nd mongodb instance. I first upgraded my plugins to the latest, ran ./nodebb upgrade while on 0.7.3

I then:
git checkout v0.8.x
git pull (just in case)
./nodebb upgrade

running in dev mode just crashes and relaunches when hitting the categories page. When I first installed the forum, I was using v0.8.0 and switched to v.7.x since the plugin support wasn't updated yet.

I am using the Vanilla theme and it upgraded to 4.0.8 after switching to v0.8.2
