IPlanet 4.0 upgrade

Hi,

I am in the process of transitioning some web applications (java, oracle) from another company. Theses applications currently fun on iPlanet 4.0.

I am not able obtain a license key for iPlanet 4.0 so cannot install it on my server.

Does anyone know if I can simply upgrade to current version or a supported version with no changes to my applications?

Any information would be greatly appreciated.

Thanks.
