Application Object Toolkit 2023 R2: Is it possible rework / Change Objects which are developed with AOT Version 2014 within that version?

Application Object Toolkit 2023 R2: Is it possible rework / Change Objects which are developed with AOT Version 2014 within that version? Background: AOT Objects where created for a 2014 Galaxy. It was a big issue as the Galaxy has been migrated to version 2017U3. Because the AOT Objects could not be changed in that version as there was no AOT available. They are planning the migration to 2023R2SP1P02 now. AOT 2023R2 is available. Is it possible to rework the 2014 AOT Objects within that version?

Thanks in advance!
