Hi
I migrated an hospitality software from Tbred 8.3 to ProvideX 4.01 in 1998.
At that time, the migration tool was creating a big bundle text file with all your programs and data files (depending on the directory devices you had selected for migration)
You then moved this big ass file to the target environment / system and used the unbundle tool to recreate programs and files in ProvideX format.
Almost all incompatibilities were addressed by the conversion tool, and fixing those that remained only took hours (do not have the details, as it has been 23 years). Even if you were using the Tbred « Windowing » system which we did not, and is quite different from ProvideX windows and dialogue controls, the conversion tool was modifying your code to call emulation routines provided by ProvideX.
During the transition period, you can use the various emulation modes provided by ProvideX (such as the Tbred FID() format, the windowing emulation, etc…) but it is then recommended to change your code to move and stick to the ProvideX standards and conventions. Who would want to migrate to another BB once under ProvideX anyway ?
