...
- The target server has the same app, same process(es), and have been tested to be working end to end (with all integrations, and plugins fitted in). This is so that discrepency in app/process design can be ruled out in case of any problem arised later on.
- The target server has the same user management, so that the same user assigned, in current server, can be found in target server. This is so that problem that may arise when assigning an user can be ruled out.
Performing the Migration
Copy Form Data
Migrate non-process data over first by copying them over. Remember to copy and not to move, so that the original server remains fully functional and intact.
- Make a list of process instances that are still running.
- Copy these data over to the target server.
- Form Data from the database
- File Upload from wflow/app_formuploads
- Now that form data and its uploaded files are available in the target server, we can migrate process instances over to the target server.
Migrate Process Instances
Then, perform the follow steps, starting with just 1 process instance.
...
Once we have validated and refined the steps to migrate a process instance, we can then move on to migrate more process instances over.
We have created an utility app to perform the 3 steps listed above. Please refer to the diagram below to understand on how to use it.
