Details please, or we aren't going to be able to even think about how to
solve this for you.

BTW You can also do a xend migration to e.g. 4.2 (using the xend whichis
in 4.2) and the use 4.2's xl to do a localhost migrate or a second
remote migrate to another 4.2 system.

xend's deprecation has been on the cards, and widely known, for several
releases now. It is time to quit stalling and start moving. I intend to
post a patch deleting it as soon as 4.4 is out the door.

Of course you are also free to pick up xend maintenance if you really
want to keep it alive. We could for example move it out of tree. And by
"We" I mean "You and those others who are interested in continuing with
xend".
