Porting a design from one technology to another (even the finished layout)

Hello,

I'm looking for help in porting a design from one technology to another (both fairly similar 180nm CMOS) and I already have routines to translate schematics and match up corresponding pCells. However, I'd like to know if the same thing can be done for a layout. Is there any information out there for translating a finished design into a new technology and keeping the connectivity and pCell information for the layout as well as the schematic?

I'd found this post from six years ago but I can't get to the COS solution mentioned and the discussion just sort of peters out.

Is what I am trying to do not realistic or are there some basic elements that already exist that could help me.

Thanks for the help if anyone has any suggestions.
