We are using Worklight enterprise 6.2 with fix packs and we are planning to upgrade to 6.3 in the next month (beginning of May 2015). However, we see now that IBM is about to release MFP 7.
Can you please clarify to me those queries:
What is the impact on the project which has been developed on version 6.2 to be moved to 6.3 or 7?
What is the recommendation for us in terms of upgrading, should we go immediately to WL7 or to 6.3 first?
We are very close to the production and our concern that the WL7 "might" be unstable or contains issues that we might face in a critical time."Feedback would be appreciated"
MobileFirst Platform Foundation 7.0 is not about to be released - it is already released.
Lots of changes in both 6.3 and 7.0. Read the documentation to see what's changed...
6.3: http://www-01.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.getstart.doc/start/c_release_notes.html
7.0: http://www-01.ibm.com/support/knowledgecenter/SSHS8R_7.0.0/com.ibm.worklight.getstart.doc/start/c_release_notes.html
In terms of your project structure, starting 6.3 the adapter thread pool has been removed and you are now in complete control of it. Your adapter XML will be upgraded to the new structure.
In terms of technology, starting 7.0 there is REST support together with a new authentication mechanism - OAuth. Classic authentication is as before and is still there. There are also now Java adapters in addition to JavaScript adapters, and lots more.
7.0 is indeed new, but provides you with a lot of new possibilities.
6.3 is very stable (that is not to say that 7.0 is not stable, but it's also very new).
We cannot decide for you if to upgrade or not, it sounds like you are already considering the right things to consider.
Read about the two releases.

Currently I have a single DC cluster with 3 nodes running 4.1.7 version of Scylla. This setup has been running for a long time and I don't want to make changes to this DC, if possible. Now I have a requirement to add another DC cluster with 3 nodes. Can I set up this new DC with the latest stable version of Scylla? Will the two DCs be able to communicate with each other without any issues? Or am I forced to upgrade the existing DC to the latest version?
Scylla supports rolling upgrades, which means you can indeed upgrade just some of the nodes in the cluster while the rest are still running the older version. The cluster should be able to fully work in this state - including the communication between old and new nodes. Not all upgrade paths are equally supported or have been equally tested, obviously, but most "interesting" upgrade paths (a newer release in the same major version, the next major version) are indeed supported.
That being said, while staying at a half-upgraded state for a long time is possible, it is not recommended. It also means that whatever new features or improved algorithms were introduced in the new version, the new nodes will need to avoid them until the full cluster is upgraded.
OSS 4.1.7 is a pretty old OSS release from Oct 2020. The assumption that you can add another DC running OSS 5.0 (latest OSS release from 10 days ago) to the existing cluster, is a bit of a risky one.
The supported upgrade path (QA tested) is from OSS 4.6 to 5.0. You can read more about the upgrade path here: https://docs.scylladb.com/upgrade/upgrade-opensource/
The tested upgrade route is via minor versions 4.1 --> 4.2 --> 4.3 --> 4.4 --> 4.5 --> 4.6 --> 5.0, jumping multiple minor version should work, but we can't say that it was tested.
I am currently involved in a project, that requires migration of 3.5 to 4.x, 4.14 is working fine. I am raising this question because, mule 2 is supporting Java 11, while mule recommended approach is to work on adoptopenjdk 8.0
https://docs.mulesoft.com/release-notes/mule-runtime/mule-4.2.0-release-notes
It is not clear exactly what is the question, however migrating from Mule 4.1.x to 4.2.x doesn't require usually changes to applications. You are free to use Java 8 or 11, though 8 is recommended.
You can upgrade from 4.1 to 4.2 without changing the code or the java version.
So the best approach to migrate would be to use the same configuration as in 4.1
Furthermore, it's a good practice to upgrade the connectors versions of your app.
There are multiple versions of IBM mobilefirst platform available. What are the different decision points that need to be considered for choosing a particular IBM mobilefirst version for implementation?
There are only two versions that should be considered at this time: 7.1 and 8.0, and the only reason to choose 7.1 is if you've already invested in a version older than 7.1. The reason I say that is because V8.0 is rearchitected in a number of significant ways that make it more suitable for Cloud deployments and Open development models. Therefore, the cost to migrate from an older version to V8 is somewhat greater than to migrate to 7.1, and 7.1 will continue to support all the latest mobile operating systems. V8 on the other hand has many new features that 7.1 will never have (as you'd expect) If you're looking to play with the technology, go download the free DevKit from https://mobilefirstplatform.ibmcloud.com/.
So bottom line: If this is a new deployment/purchase/etc. then I'd always suggest V8 as the preferred choice. However if you already have an investment in older versions, V8 is still the preferred choice, but migration to V8 may take more time than to migrate to 7.1.
Does that answer your question?
Mobilefirst 7 or 7.1 will be most reliable as of now since it has been in the market for some time and most of the pmr's would already be resolved. Within 7 and 7.1 itself there are few changes like 7 has desktop browser environment which is not present in 7.1. So you would want to check out the differences before chosing 7 or 7.1. But personally I would recommend you to go for mfp8 since there are lots of new features added into it. It might be a bit unstable but eventually everyone would upgrade to 8 is what I feel.
I am looking at Nexus 3.00 OSS Edition.
The recent release of Nexus 3.0 (OSS Edition) seems to have dropped support for rpms.
I don't see any specific note declaring that they are going to be dropping some features from 2.x.
So i am not sure whether the rpm/ yum repositry support is actually removed Or is it being supported differently with the new Nexus 3.0 or this feature has been made exclusive for the Paid version.
Not yet. The progress of this can be tracked in http://issues.sonatype.org/browse/NEXUS-10191. Feel free to watch for release details.
I heard that JBoss 7 is not certified for FreeBSD - is that correct?
Where can I find a list of supported platforms? (I spent some time googling, but was not successful)
Strictly speaking there is no certified OS for JBoss 7 as only JBoss EAP 6 is supported by Red Hat.
The supported configuration for JBoss EAP 6 (the supported version of community JBoss 7) can be found here: https://access.redhat.com/knowledge/articles/111663
As JBoss is pure java application, a compliant JDK is enough to have a supported system. So if you have the Oracle or IBM JDK running on FreeBSD is will be supported by Red Hat. But they haven't test them with JBoss.
Any way if you want Red Hat support for the EAP you better check with there representative to discus the extends of the support (if the FreeBSD JDK have some compliance bug, they will probably send you back to the JDK supplier. If you chose RHEL with OpenJDK you will have one supplier to blame for any software stack issue, no redirect to another suplier.)
For community JBoss as for other platform, you will be responsible to make it work with your stack. An good first test can be performed by running the standard compliance tests included in the JBoss sources, if it runs on your target platform and JDK it is a good sign that JBoss is working on it.
Certified Support as per Redhat only goes up to 6:

However if you look back at the release docs they have not changed. OS's are the same.
