Resuming ddrescue with newer version?

[Bug reports for ddrescue, data recovery tool.]

Hello,

I had started recovering data from an external disk using the ddrescue 
version that is available in puppylinux. Unfortunately, that version is 
very outdated (1.17, released in 2013) and the recovery is taking an 
extremely long time (I have to restart it every now and then or it stalls).

I would like to resume the data recovery I started using the latest 
version of ddrescue (i.e. use ddrescue 1.25 with a mapfile and already 
recovered data from ddrescue 1.17).

Is this possible without corrupting the data that I already recovered? 
Since the disk is 4 TB, I prefer not starting over.
