Hi, our organization is currently using a rich client desktop application developed with PowerBuilder 11.5. We would like to migrate our application to the currently available PowerBuilder 2017 or 2019. We were wondering if anyone had experiences migrating from a much older version to the currently available versions, and if you can share your general experience, recommendations, or useful guides for the migration. We've looked at a few APPEON documentation for migration but they are mostly very brief and general at best, unless there are guides.
We may also look at hiring PowerBuilder consultants depending on the result of product and upgradability assessment. If anyone has any experience hiring, or are a PowerBuilder consultant yourselves, what is the current general market hourly rate specifically for this type of migration? Quick look at ziprecruiter or Glassdoor shows a pretty big range and not very helpful for determining of pay for skills required. Any assistance you can provide is greatly appreciated.
