Migration cacti from one server to another with CMDPHP PHP ERROR NOTICE Backtrace and not graphing

[Astra312]

So I have installed new cacti (1.2.19, centos 7, php v7.1.33 and php v5.6 with fpm, rrdtool 1.7.1, poller spine). Copied old rrd files to new server with plugins. Cacti shows old data on graphs, but not recording new (nan) and data source troubleshooting not working too (endless loading). Also I observe this error in log:

2022-02-23 08:54:52 - CMDPHP PHP ERROR NOTICE Backtrace: (/graph_json.php[32]:include(), /include/auth.php[28]:require_once(), /include/global.php[553]:cacti_time_zone_set(), /lib/functions.php[6588]:timezone_name_from_abbr(), CactiErrorHandler())

I have installed and configured Cacti 1.2.23 on Centos 8 Stream. Everything was ok and working. But after migration cacti from 0.8.8b to 1.2.23 graph Cacti shows old data on graphs, but not recording new data and graph. I have followed the following procedure https://www.xmodulo.com/migrate-cacti-server.html

Graphs is still Nan. The log has given below. Your cooperation is highly appreciated in this regard.

Best Regards!

Use spine instead of cmd.php. it's much more scalable.
