Is there a way to export the existing jobs from the previous to the latest version of Centerprise?

There are three ways in which you can export the existing jobs to the latest version of Centerprise:

1. Direct export and import of schedules from Scheduler.
2. Upgrading the 7.6 repository to 8.x. This is a required step if you previously had 7.6 installed. This option preserves any existing schedules. To know more about it, refer to this article.
3. Upgrading 8.x to 8.3/8.4. This is a minor repository upgrade, and it adds some optimizations (indexes). This option also preserves any scheduled jobs.
