Graphs don't show after migration

[helpmailinglist]

Cacti was moved to a different box. Everything works fine except that the graphs are not being displayed at all.

-Cacti and the required packages reside in the same box.
-Cacti's version is the same on box boxes v 0.8.7e
-The db was dumped and restored using the following:
mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
mysql -u root -p[root_password] [database_name] < dumpfilename.sql
-Config.php is the same on box boxes.
-rra, scripts, resource, and log directories were copied over to the new box.
-Permissions on the rra and log dirs and their files are set the same and the original box.
-Original box RRDTool 1.2.x
-New box was RRDTool 1.2.x in cacti, but then changed to RRDTool 1.3.x because the Technical Support page said that the new box is running v 1.3.x

Please see e.g. /var/log/httpd/error_log.
Then, please see Graph Management, select a graph and switch to DEBUG mode. Post results
R.

apache's error log:
ERROR: This RRD was created on another architecture

Graph Debug mode:
RRDTool Says:
ERROR: This RRD was created on another architecture

I'm thinking these errors are because the graphs were created using rrdtool v 1.2.x.
How can the graphs be converted from v 1.2.x to 1.3.x?

One more thing I forgot to write down on the original post. Original OS is 32bit and the new box is 64bit.

Thanks

This issue has been solved.
Solution: Converting 32bit RRD to 64bit RRD.
http://slog.carlheaton.co.uk/index.php/ ... itectures/

One important note though: 32bit OS has the 128kb command line memory limitation. Using ls command on 4000+ rrd files will return "Argument list too long". So the fix is use the find command on the 32bit OS--find [path] -name "*.rrd" -exec rrdtool dump {} > \; {}.xml \;
The ls command in the 64bit OS works just fine in 4000+ files.

Thank you gandalf for helping out!
