You don't say exactly what you mean by "my packages". If you copy *all* R 4.5 packages to the default R 4.6 library directory, you will probably damage R beyond repair. You need to remember that packages with priority "base" contain code that implements R internals. Trying to use R 4.5 internals in R 4.6 will cause a lot of problems.
If you only copy contributed packages (i.e. ones that you installed which get priority NA, or recommended packages) then what you did might work, but it's safest to just save the names of all contributed packages, and reinstall those.>
Since then, I see the following behavior: Each time I run "update.packages(ask='graphics',checkBuilt=TRUE)" I am asked TWICE "--- Please select a CRAN mirror for use in this session ---". And, more embarrassingly, all my Cran and Bioconductor are said to require an update. That also happens when I run "update.packages", say, one hour after my last update.
I think others have pointed out that every contributed package *does* need an update when going from R 4.5.* to R 4.6.*. You can only get away with keeping installed copies of packages when you stay within the same minor version number, e.g. 4.6.1 to 4.6.2.
