If you are converting a network of SunOS release 4 systems to the Solaris 7 software, decide the order of the systems to convert so that you do not inconvenience for the users. For example, you might want to convert all client systems before you convert any servers. The first system you convert should be a standalone system with a locally attached CD-ROM drive.
For a while, you will probably manage a network consisting of both SunOS release 4 and Solaris 7 systems, and part of your planning should involve determining priorities. For example, you may want to convert one domain and use it for system administration testing and for porting internally developed applications before you convert the entire network environment.
