Reinstalling PHP

Hi, I am running SUSE 9.2 with PHP 4.3.11 (with Apache2 and MySQL 4.0.21).
Unfortunately PHP was configured with sessions and mysql support disabled,
so I want to change this with minimum of hassle. I don't want to risk
breaking any current PHP scripts or dependancies on my server.

I used phpinfo(); to get the current configuration of PHP
I downloaded the sources for PHP 4.3.11
I ran ./configure using the same configuration as reported in phpinfo(); but
enabling sessions and MySQL
I then ran make

So far so good. No errors. I understand that all I need to do now is run
make install and restart apache.

What is the chances that this will work without any problems, or is this
likely to break things?
What can I do now before installing to enable me to revert to the current
PHP in case things do break? How could I examine the makefile to determine
which files would be replaced, so I can back up the existing ones, for
example?

Thanks for the help!
