It depends on your version of the os. I went from 32bit RHEL4 to 64bit RHEL5. So I had to" rrdtool dump" all the graphs and restore them on the 64-bit system.
If you are going from 32bit - 32bit or 64 to 64, you should be fine.

Is there anything we need to do to avoid losing graph data?
I saw an earlier poster warning about this.
We're running 4.3.2 and planning to jump to 4.3.7 , server is RHEL linux
