upgrade to solaris 9 - mysql impact

I have 4 solaris 8 servers running mysql 5.0.22. I am considering upgrading to solaris 9 and wanted to know if mysql needs to be recompiled for mysql to run under solaris 9.

Thank you

No it doesn't need to be.

Thank you for your response. I have other apps too, apache, proftpd, etc. What about those?

Have you had success upgrading without the need to recompile everything?

Thanks

yes, they are binary compatible.

thank you very much and I will give it a try and see how it goes.
