I've been trying to upgrade my ember app from 2.18 to 3.4.4 and I just want to know if I chose the correct ember version which is 3.4.4? Any response is much appreciated. Also what are the disadvantages or issues I may face if I jump from 2.18 to 3.8.1?
My personal recommendation is to upgrade from one LTS to the next LTS version. There's a great video from Ember Map that discusses a great strategy for upgrading your ember apps which I will summarize here in case the link ever goes stale.
Upgrade all forwards-compatible packages
Upgrade 3rd-party dependencies and addons, one at a time
Upgrade Ember CLI and friends using ember-cli-update
And in my opinion, use ember-cli-update --to next-lts-version-here. Once you upgrade to the LTS, fix deprecations and tests until all green, and then continue. I used this process to go from 2.16 -> 3.8 over the weekend
The latest long term support is 3.8. here is release cycle. You can jump to 3.8 if suits you.
There is a addon named ember-cli-update. It applies changes automatically. Also you can checkout the ember-blog to learn changes.

Will there be any issue in my current notebooks and jobs if i upgrade my Databricks run time version from 9.1 LTS to 10.4 LTS
I didn't tried upgrading the version. If I upgrade it then will I be able to change it back to previous version
It's really a very broad question - exact answer depends on the features and libraries/connectors that you're using in your code. You can refer to the Databricks Runtime 10.x migration guide and Spark 3.2.1 migration guide for more information about upgrade.
Usually, the correct way to do is to try to run your job with new runtime, but using the test environment, where your production data won't be affected.
I am trying to upgrade my Ionic environment to the latest version.
I have an existing app I built on Ionic 2.0.0-beta.32. I want to upgrade it to the latest version 2.0.1 (or the final release).
My questions are :
1) How can I upgrade my environment ?
2) Is there any changes I have to do in my code ? (if yes please can you tell me exactly how to proceed it... ?)
answering question 1:
try these in the root of your project
sudo npm install -g ionic
ionic lib update
question number 2 is hard to answer. generally you should be good. You should try running your code and do some regression testing and then ask specific questions if you face any problems.
Ionic provides upgrade instructions in their changelog. Usually it is enough to upgrade your package version, but sometimes when there are breaking changes that you need to manually address they will be listed on that page.
I would like to update an addon to the long term support release channel using ember-cli. How do I do this?
I know I can put a different version of ember and ember-data in de bower.json and package.json files. But will updates of ember-cli not interfere with these older versions?
Also what is the lts release of ember-data?
The current LTS is 2.4, so you need to open your bower.json and in the ember line, put the following:
"ember": "~2.4.0"
This should install the latest 2.4 at the time of the install.
But will updates of ember-cli not interfere with these older versions?
Ember CLI is mostly decoupled from Ember itself, so it can be used with almost any version. When ember.js is converted into an addon (like what happened with ember-data), you'll need to mind the update instructions for it, so you continue to use the bower package instead of the npm addon.
At the moment Ember Data does not have an LTS.
What is the recommended way to upgrade Ember from version 1.13.8 to version 2.3?
I have seen an example on this link How to upgrade the Ember version in an Ember CLI application?.
Is that the only thing that I have to change?
If you want to fully upgrade your application and dependencies, I recommend following the instructions on the ember-cli release post.
If you only want to upgrade Ember.js itself, the version in bower.js is indeed the only thing you need to change.
I am trying to upgrade a Couchbase Community server that is currently running 3.0 to 4.0. I am using the 'Amazon Linux' on AWS, and have used the CentOS 6 build to upgrade from 2.5 to 3.0 - that upgrade was super smooth. According to the documentation, I should be able to go from 3.x to 4.x just fine as well.
http://developer.couchbase.com/documentation/server/4.0/install/upgrade-matrix.html:
Upgrade from the latest version 3.x directly to version 4.x using any supported upgrade strategy.
But I get the message
couchbase-server conflicts with couchbase-server-community-4.0.0-4051.x86_64
I have found that the couchbase-server name is now reserved for the enterprise edition, and couchbase-server-community is now used in 4.0 for the community edition, which would explain the conflict. https://issues.couchbase.com/browse/MB-15716
Is this really an upgrade-breaking change? I cannot find any documentation on how to resolve this change short of uninstalling and reinstalling.
If it were me and since you are on AWS, just spin up new instances, install Couchbase on them and do rebalances where you add one in and remove an old one (1 in, 1 out or 2 in, 2 out, etc.). With the same amount going in and out of the cluster, the cluster will do a swap rebalance which is the most efficient. All of this can be done while up and serving traffic. This is a very standard upgrade path and the recommended approach when in the cloud.
Once upgraded, discard the old instances. Yes you are running more instances at the same time during the upgrade, but for the cost of a few lattes you are upgraded smoothly.
I have experienced the same conflict when trying to upgrade from Community version 3.0.1 to Community 4.0.0.
It is worth mentioning that if you uninstall the 3.0.1 version and then install 4.0.0, all your buckets and their data are kept. Maybe there are some cases where this would fail, always good to take a backup first, but in my case the transformation was smooth.
This was on my developer machine, for a cloud installation I really like the swap in/out which means you can do the upgrade without interruption of the service.
