I have a requirement where Client wants to migrate or replicate running instances from One environment to another. We had showcased one approach for POC purpose to store running instances data in DB & fetch the same data in the new env & retrigger the process models using start process smart service. But the problem is this solution isn't Generic there are a lot of changes we had to make in the existing process models.Is there any way to achieve this using something Generic as client is expecting some generic solution or is there anyway we can migrate the running instances from one environment to another.Thanks Tanvir

Hi Tanvir,the detailed course of action depends where your instance is running at - on Cloud or on-premise. The generic schema would be:Check-pointing all your engines. Shutdown source environment Backup database, documents, kdbsShut down target environmentCopy above items to the target instanceBring up target instancePlease be aware that this approach moves all active instances from the source environment to the target environment and overwrites prior existingtasks in the target environment.A more selective way would be maybe calling APIs in the target environment, starting the desired process model there. Which of course requires some changes to existing process models.
Thank you juergeng393 for your suggestion. we will definitely discuss this option
We are moving from on-premise to cloud. So the cloud environment will be newly setup
In order to achieve this upgrading as per the following documentation is the only supported method:
https://docs.appian.com/suite/help/19.3/Upgrade_Guide.html
However, instead of moving between a lower to higher version as per the above guide, you will need to move between the same exact versions.(Same Hotfix as well). Hope this helps.
If you are moving from on-premise to cloud, I would recommend contacting your account team or opening a support ticket. Appian can help you with this migration and can provide the right steps for your environments.
thank you Peter
