I would like to make the support a bit more general
this, allowing
for links such as:
[/page page]
How about using an interwiki link?
Go to your mySQL prompt and type:
INSERT INTO mywiki_interwiki (iw_prefix, iw_url) VALUES ('other',
'../myOldSite/$1');
Then when you want to link to the other site you do:
[[other:link.html|Click Me!]]
