Each process in the workflow, each task, each instance, and so on, has a unique ID. These IDs are randomly generated. The uniqueness of the ID makes it unnecessary to confuse each process.

 If the workflow system changes the database, it is equivalent to a new system. The ID will start again randomly. The process ID in the database is duplicated before the meeting.

Therefore, if you have already used the workflow to report, you need to migrate all the previous workflow database tables to the new library when you replace the deployed database. Otherwise, there will be duplicate IDs and an error will be reported.

 If you do not move the old table to the new library, you will need to re-subscribe a database. Otherwise, when the ID is repeated, all the data that meets the ID condition will be taken out for approval.
