I have a lot of programs that use INDY 9 in BDS2007. I'm porting them to Delphi 10.4 but here there is INDY 10.
It is possible to remove INDY 10 (unused at moment) and install/compile INDY 9 in Delphi 10.4? Before making mistakes I ask if someone already made that with success.
Best regards Silverio
Indy 9 is NOT compatible with IDE/compiler versions after BDS 2007. Beyond that, you MUST upgrade to Indy 10. Everything you can do in Indy 9 can be done in Indy 10, though the syntax may be slightly different, depending on what functionality you are using exactly.
