vim: keep undo when moving a file?

[ping song]

I have a file that I keep using for quite a long while, it's convenient to keep the editing history forever, so if something gone wrong I can always undo back and locate the issue.

today I moved the file to another folder and all undo history gone.

I tried to rename my original undo file according to the new location , but still not work...

anyone has a good solution?

this is my undo related config in .vimrc , I'm running latest vim 7.4..

set udf

if exists("+undofile")

  " undofile - This allows you to use undos after exiting and restarting

  " This, like swap and backups, uses .vim-undo first, then ~/.vim/undo

  " :help undo-persistence

  " This is only present in 7.3+

  if isdirectory($HOME . '/.vim/undo') == 0

    :silent !mkdir -p ~/.vim/undo > /dev/null 2>&1

  endif

  set undodir=./.vim-undo//

  set undodir+=~/.vim/undo//

  set undofile

"  set undolevels=1000         " maximum number of changes that can be undone

  set undoreload=10000        " maximum number lines to save for undo on a buffer reload

endif

I just realized that a plugin I enjoy using, vim-eunuch, does allow the
history to be saved when you move or rename files. It defines a handful
of ex commands for Unix-like file operations; the ones I'm talking about
are of the form

:Rename newname

and

:Move newfolder

(you run those while you have the file open and it moves it in place).

If I am not mistaking to move file A to location B keeping undo
history you need to

:saveas B
:bwipeout! A
:call delete('A')

I.e. copy file to the new location by saving it there (creates new
buffer), drop old buffer and delete leftover copy of the file at the
new location. Plugin that was referenced by @Eric Christopherson does
something like this, but it also seems to cover some corner cases.
