OLD urls in serialized array

Hi,

I’m using the plugin to replace the staging URL to the Live site URL.
It works nice, but for two plugins (‘Ajax Search Lite’ and ‘Google XML Sitemaps’) the serialized array contains the OLD url.
This happens in the wp_options table for the :

1. ‘asl_options’ option name for the ‘Ajax Search Lite’ plugin
2. ‘sm_status’ option name for the ‘Google XML Sitemaps’ plugin

Is there a setting to change these also?
Should I do it manually every time, catering for the string length (s:) in the array?

Thank you,
