Upgrade of custom application
we are a company located in central Germany working with Intersystems Caché since 2003 (Jesus, that's actually a long time in IT).
As we struggle to keep pace with outside development we still operate on Caché 2013.1
We are, of course, aware that we need to upgrade Caché and therefor plan an upgrade to 2017.2.
Now my question to you bold ObjectScript warriors:
- Did anyone do this with a legacy application (still have macro routines, the old style)?
- Has anyone experienced any bigger issues with a move like this?
- Are there existing checklists apart from https://docs.intersystems.com/cache20172/csp/docbook/DocBook.UI.Page.cls... ?
- Is there even a freelancer out there willing to help identify migration issues?
Our application is a medium sized ERPish application with around 250k lines of code. So a bit code to review.
Many thanks for your input in advance and best regards,
