Yes, especially this time, since the toolchain has been updated.

My favourite procedure for this goes like

(pkgs <- .libPaths())
(pkgs.old <- sub("3.4", "3.3", pkgs, fixed=TRUE))
(pkgs.new <- setdiff(list.files(pkgs.old), list.files(pkgs)))

Check for sanity(!), then install.packages(pkgs.new). Things may need modification if yor setup involves personalized libraries, multiple repos, etc.

Just copying the entire directory followed by update.packages(checkBuilt=TRUE) will overwrite packages from the installation of 3.4 and not all of those are CRAN based.

[To tell the truth, I don't usually practice what I preach. I just install the missing packages when it turns out that I need them...]
