Does sstabloader work between datastax cassandra and apache cassandra?
I'm trying to copy data from dse 5.0.7 to apache 3.11.1 cassandra version
It shouldn't be an issue to use it to export between Datastax Cassandra and the open source version, if they are the same versions.
Having said that, please note that DSE 5.0.7 uses Apache 3.0.11, as explained in the release notes. This means that you should import the data to a cluster with that version, and once that this is completed, upgrade to 3.11.1.
Disclosure: I'm not a DSE user, I don't have a way to test this.

I needs to upgrade Cassandra dse version 4.8.16 to 6.0.6 for my Cassandra cluster. Please provide me steps to do it.
I did exactly same thing.
But it is not possible directly:
You must upgrade DSE from 4.8.16 to 5.0.15 & run sstableupgrade in the end.
1 Problem in doing above: you must move all you client applications to CQL from thrift(if any). However documentation says: it is ok to have Thrift in 5.0.15 but that is not correct(specially for my case).
Once you are on DSE 5.0.15 you can jump directly to DSE 6.0.6 or DSE 6.7.2 as per this link. Here also you need to run sstableupgrade.
In whole upgrade process, you need to take care of Driver's compatibility.
Currently I have DSE 4.6.7 with Cassandra 2.0.14. I am building another cluster with DSE 5.1.3 and cassandra 3.11. I would like to migrate the tables from DSE 4.6.7 to DSE 5.1.3. Will that work.
Instead of upgrade of existing cluster. I am creating a new one and would like to migrate the data. Will that work.
Anyone know any good open source database management tool like Opscenter for Apache Cassandra? Opscenter only work for Apache Cassandra version 2.1 below but we are using Apache Cassandra version 3.5 so Opscenter wont work. Thanks Phuong
I've having some issues with my Cassandra cluster and I would like to install OpsCenter Community in order to debug what's going on.
I've found this and this pages talking about the compatibility between DataStax OpsCenter and Cassandra, but this don't list Cassandra 2.2.5 (actually I'm using DataStax Cassandra - dsc 22).
My question is: can I use DataStax OpsCenter (free / community version) within Cassandra 2.2.5? If not, there's an alternative?
No, the docs you cited indicate that OpsCenter doesn't support any cassandra greater than 2.1.x and the next version of opscenter (6.x) will only support Datastax Enterprise. I don't know of another visual front-end to cassandra at this time.
I have been building an application using Apache Cassandra 2.2.0 for sometime now. We plan to start using the DataStax Enterprise 4.8.5 (this is built on Apache Cassandra 2.1.3).
Problem is as this is a downgrade of Cassandra version, 2.2.0 -> 2.1.3, I am not able to read the SSTables created by Cassandra version 2.2.0.
What can I do to have my old data available with DSE 4.8.5?
This is not supported. You should consider contacting Datastax for advice (that's one of the advantages of paying for DSE, you get someone to talk to about topics like this).
You'd almost certainly have to export the data and re-import it (either using sstable2json or COPY TO+COPY FROM to export it to a CSV using CQLSH, or using something like Spark or CQLSSTableWriter to recreate 2.1 sstables.
