Compiled Haskell libraries and GHC installations are not generally relocatable to a different path. So in theory copying ~/.stack between machines should work if your home directory is in the same place on the filesystem (and the architecture matches), but won't work if your home directory changes.
Just checked Removed from ~/.stack/programs/x86_64-linux both - ghc.7.10.2 (directory) - ghc-7.10.2.installed And reran $ stack setup The messages seemed to say something the the effect "already downloaded" Spent some time setting up... And now $ stack ghci seems to be working. Also now all references to the old username on grepping in ~/.stack seem to have vanished So is this ok or improper... ??? May the experts opine!
