[rrd-users] Migrating RRDs from rrdtool-1.3.8 to 1.2.27

[Steve Shipway]

The best thing to do would be to upgrade your new server to RRDTool 1.3.x (or even 1.4.x) and the problem would go away.

I know you say that your software is dependent on RRD 1.2, but RRD 1.3 and 1.4 are backwards-compatible so there should be no problem with them using the 1.3 or 1.4 libraries.  The only difficulty I could imagine would be if the software has the 1.2 libraries somehow built-in, and so it would not be able to process v3 RRD files as created by RRD 1.3 or 1.4.

Does the RRD file in question use any of the features not present in RRD 1.2?  For example, the special RRA types from Holt-Winters and so on?  If not, then you could probably edit the XML dump to make it pretend to be a v2 XML dump and then load it in... although I've never tried this, my initial thoughts would be that it would work.

Subject: [rrd-users] Migrating RRDs from rrdtool-1.3.8 to 1.2.27

I have an old server I am about to retire.  It was running rrdtool 1.3.8.  My
new server actually runs an older verion of rrdtool, 1.2.27.

old server:
rrdtool-1.3.8-1.fc10.x86_64

new server:

rrdtool-1.2.27-3.el5

Dump and restore did not work.  I get error messages like:


rrdtool restore lrrr_load_1min_400.xml lrrr_load_1min_400.rrd
ERROR: Incompatible file version, detected version . This is not supported
by the version 0003 restore tool.

Other applications installed on the new server depend on 1.2.27 version of
rrdtool.  Is there another way to complete the migration?

Thanks.
