Upgrading Rundeck from 3.0.27 to 3.4.7

We are trying to upgrade Rundeck version from 3.0.27 to the latest version (3.4.7)
We got below questions,
What is the approach to upgrade from 3.0.xxxx to 3.4.7? Could we do a direct upgrade or otherwise, if we have to run through multiple intermediary versions, what are those?
Does upgrading from 3.0.xxx to 3.4.7 fix the log4j vulnerability?
Please help to clarify above.
Thanks
Due to the big gap between 3.0.X and 3.4.X (and the upcoming 4.0.X) the best way to upgrade your instance is to create a fresh 3.4/4.0 instance and then import your projects and keys (exported previously), as a tip, try this on a non-prod environment first.
Rundeck 3.0.x uses log4j 1, so, even if the vulnerability doesn't affect explicitly the log4j 1.x EOL was in 2015 and isn't supported anymore, so, it's important to move to the latest version (Rundeck 3.4.10 at this moment).

cassandra migration from version 3.9 to 3.0.X

we have a cassandra node with 3.9 version.
Is it possible to migrate to last stable version (3.0.11)?
(we dont use any special feature of 3.9.)
Please read downgrade session of this guide:
https://wiki.apache.org/cassandra/CompatibilityGuarantees
The main part:
Downgrading is only guaranteed within minor releases and only to the previous bug-fix release
Theoretically you can try downgrading 3.9 -> 3.7 -> 3.5... etc, but there is no grantees that this will work and will not do problems in the future. Test in some dev environment if you have to do it, or stay with 3.9...

How to upgrade datastax enterprise server 3.0.2 to 4.0?

What is the correct procedure of upgrading Datastax enterprise server. We have the datastax 3.0.2 running and we need to upgrade it to 4.0.1.
Can it be done using the Opscenter UI? Or do I need to manually upgrade the package on each machine.
Thanks.
There are pretty good upgrade instructions in the docs: http://www.datastax.com/documentation/upgrade/doc/upgrade/datastax_enterprise/upgradeTo4_0.html
You will need to manually upgrade each node, and it will take two upgrades, as you have to first upgrade to the latest DSE 3.2 release (3.2.6 right now), then upgrade to DSE 4.0 (and you should go to the latest which is 4.0.3 right now)

Upgrading Cassandra from 1.2.10 to 2.0.1

I am trying to upgrade a cassandra single node installation from 1.2.10 to 2.0.1.
I am using still the old RandomPartitioner, I change all the parameters in the cassandra.yaml file. But when I tried to start the node I get this error:
java.lang.RuntimeException: Can't open incompatible SSTable! Current version jb
In the notes from the documentation I can not find anything related with the change in the SSTables, did anyone deal with this problem?
If you guys had previously upgraded from an earlier version to 1.2.10, did you guys perform a 'nodetool upgradesstables'? This would have upgraded sstables to prevent possible incompatibilities.
The upgrade procedure from 1.2.9 to 2.x does not seem to recommend running it, so those sstables should be compatible, but trying it again might be worth it.

Upgrade Cassandra Version Brisk

How can I upgrade the cassandra version and thrift version in Brisk?
Is there any tutorials kind of stuffs avalailble? I changed the build.properties file but on build, the version I mentioned couldn't be located at any repository.
Im trying to upgrade because of Cassandra Insertion Error
this issue im facing. I hope the comment mentioned there helps
What is the latest version of cassandra that brisk supports?
In support forums I see people mentioning, replace the jars. I don't understand where should I do that.
Thanks for Help in advance
Regards,
Tamil
Finally I found the way to upgrade Brisk's cassandra version.
I Downloaded apache-cassandra-0.8.6-bin from apache site.
Copied
lib/apache-cassandra-0.8.6.jar and lib/apache-cassandra-thrift-0.8.6.jar
to
brisk-1.0~beta2-bin/resources/cassandra/lib/
and removed the older version's cassandra and thrift jars
and just restarted brisk with ./brisk cassandra
and tried this
$ ./nodetool -h x.x.x.x version
ReleaseVersion: 0.8.6
So, I hope there won't any compatability issues, since in a forum a brisk dev mentioned tat brisk core works independently against cassandra core. But I'm yet to know the way to do it by building from src rather replacing jars in bin

Tamil
