<font face="sans-serif" size="2">As the systems are both Linux, are
same-endian
(i686). and same FS (ext3?), I can only surmise that you should be able
to just copy the RRD files.</font>
<br>
<br>
<font face="sans-serif" size="2">If they are not compatible then the
updates will fail as rrdtool will not be able to read the existing
format.</font>
<br>
<br>
<font face="sans-serif" size="2">As far as actually converting them
goes,
I kind of did it on the fly so don't have any useful scripts to pass on
:-) It's pretty easy and the RRDTOOL website does provide examples

Ok cool so basically the graphs stop updating if theyre NQR after the
move, I guess thats pretty effortless to test, move a host onto the new
box and come back in a day and see what happens I suppose.<br>
<br>
As for the import/export I did the the convert to xml bit but I wasnt
sure if thats what I was supposed to be looking at. <br>
<br>
Wicked thanks for the input guys, has certainly cleared some things up,
confirmed some things, and alerted me to things I probably never would
have thought of and then gone 'uhhh wont doesnt this thing work'<br>
<br>
THanks all<br>
<br>
