[rrd-users] How do I move my rrds to my new MRTG system.

[Mersberger, Robert]

 Yes, one machine is i686 the other x86_64. I will look deeper into rrdtools to get this done. Are you aware of how I can do this, (dump and restore) in bulk rather that one rrd at a time?

Thanks for responding.

hi

i guess the problem is one machine is i686 the other x86_64

a quick google revealed this

quote:
"RRD files are endian-specific, for performance benefit ... 
When you want to copy/move from one platform to another, you can use "rrdtool dump" to convert them to a portable XML format, then "rrdtool restore" to restore them to a binary format appropriate for the localhost.See "man rrddump" and "man rrdrestore" for details."
