I use MATLAB Version: 9.7.0.1190202 (R2019b) and got "error using eval. unrecognized function or variable 'renamevars'. Can it be that renamevar function was introduced after 2019b?

If one had a comprehensive set of the installation material, that might at least have the potential to be significantly more complete than other approaches. I mean, squeezing harder won't get legacy or toolbox-related information out of release notes if it's simply not there.
As far as I can see, the available options are all significant challenges in terms of effort and time, and they all lead to a result that is not only likely incomplete to an unknowable degree, but thereafter requires biannual maintenance as well. As I think Star Strider mentioned, you may also have to (programmatically) identify and deal with cases where functions changed name or moved from their original toolbox to the base toolbox. Whether that degree of rigor is warranted for an incomplete database probably depends on how incomplete it's assumed to be.
