DT2c.. Using an old project to start a new one.

This may not cover all elements of the process, but it illustrates what I did on one occasion!

I had DD06 up and working well. I wanted to make a new program which was an adaptation of DD06. The adaptation will be called DD07 here.

First I created a folder for DD07.
Then I got Delphi running, and did File|OpenProject, and opened DD06.

I then did File|SaveProjectAs, and when the first box came up, I changed to the DD07 folder, changed the default DD06.dpr to DD07.dpr. (Only one thing SEEMED to need saving, but this was misleading... Delphi was 'helpfully'(?) 'remembering' that the .pas file for this project was back in DD06's folder... not what I had in mind!

To fix this, I clicked on the DD06u1.pas window, then did File|SaveFileAs, and changed the folder and name of DD06u1.pas to DD07u1.pas, and ran the project again. That seemed to give me all the right files, and the .exe file was now DD07.exe.

However, there were still references to DD06f1 in various places.

Next, I used the object inspector to change the name property of the form from DD06f1 to DD07f1. N.B.... trying to edit the source code to change references to 06 to say 07 is not a good idea. And I re-ran the program.

Now all references to DD06 seemed to be okay. If you referred to DD06 anywhere in comments that you wrote, I doubt they would be changed... but neither would they prevent the program from running. Perhaps now you might want to use Delphi's editor's search and replace, just to see if any references to DD06 remain.
