Planing to upgrade Activiti 5.15, which is the latest stable one 6 or 7 ?

jdp

Hi,

Currently we are using Activiti 5.15 version with multiple instances/Activiti engines. Now we are planning to upgrade Activiti version to the latest stable one as there are lots of improvement has been done since then. I have searched and found that the Activiti 6.0 is the stable one but 7 is also released. Can any one please advice which one is more stable, which I can go for ?

Thanks,

Paresh

I'm currently looking at porting some development work to 6 & 7. Couldn't comment on stability, but in terms of code migration it appears 5 to 6 is relatively straight forward. The move to 7 can be more involved, based on the questions and comments I've seen on the forum, perhaps not surprising given version 7 adopts cloud native concepts and a new architecture.

Thank you for your reply PaulT.

Can anybody share your feedback about Activiti 7 in case you had migrated from older Activiti version to 7. I am still confused about which version should I pick to upgrade, Activiti 5.15 to 6 or 7 ?

Thanks,

Hi,

Finally we have decided to upgrade Activiti 7.0.0.GA : Release 7.0.0.GA · Activiti/Activiti · GitHub

Seems this is the latest stable version of Activiti series 7.

Can anybody provide expert advice on this ?

Also, I did not find any ready to run package for this version to evaluate it. I would appreciate if anyone can direct me to get that link.

Thanks,

Paresh Modi‌ - thanks for going with Activiti 7!

re: expert advice - it may be best to start asking the questions you have and let's see if can answer them within the community.
re: ready to run package - the place to get started is here. There are Jenkins X Quick Starts available for EKS, AKS, and GKE. What is your target Kubernetes environment?

Hi Paul,

Thanks for the suggestion.

Actually we are not using cloud based architecture. We have integrated Activiti engine within our Spring based micro service and we are planing to go ahead with same environment with code base of latest Activiti 7 version along with latest modeler app to design workflows.

However few components are not supported yet in Activiti 7 like Timer & Boundary Timer and there are already running workflows in our platform with these components, so how can we manage it.

Seems Activiti 7 is still under development and not mature enough to use for production environment.

Do you have any suggestions/advice for the same ?

Thanks,

Hi Paresh,

Activiti 7 is composed by Activiti Core and Activiti Cloud. We are putting all the community effort on the cloud approach. There is no pre made package to evaluate or run, mostly because we are focusing on production ready building blocks instead of a demo app. Having said that, you can still use the libraries (if you embedded activiti in your spring microservices), we have done some work on Activiti Core 7 to make sure that the library aligns with Spring Boot 2.x and for that reason things such as security is now handled fully by Spring.

Regarding migration, it for our 7.0.0 release we focused in the new shape of the Java APIs, making sure that there is a seamless transition to the cloud approach, this means that you have still access to the OLD 6.x APIs.

Regarding the Activiti Modeler app that we are building, is focused also in the cloud approach, that means that the BPMN elements that are enabled to be used are the ones that are fully supported by Activiti Cloud. If you are planning to work with Activiti Core, you should be fine by using the Activiti 6.x app to model your processes.

Hope this helps.

Hi Salatino,

Thank you for your reply, it is really helpful.

I would appreciate if you can answer few queries below and help us to finalize approach for Activiti framework upgrade:

1. From your response what I concluded, Activiti 7 cloud is not useful for us as we are not using cloud based architecture, right ?

2. So in this case, we are planing to upgrade back-end code base with Activiti 7 Core libraries and will continue using same modeler app of 5.15. Definitions designed by Activiti 5.15 will work with Activiti 7 Core libraries ? and also same for already running workflows ?

3. However in basic analysis of code, we have found that few classes are not available in Activiti 7 Core libraries which we had used from Activiti 5.15. How can we manage usage of these classes ?

Hi All,

After analysis and internal testing we got to know that Activiti 7.0 does not support running workflows of Activiti 5.15. So will check for 5.15 to 6.0 first.

Does Activiti version 5.XX to 6.00 upgraded sucessfully?
if yes, Colud you share me what are the changes need to be done for this?
