how do you properly change the IP address of a system?

I have several systems running Solaris 10 x86. In the /etc/hosts
file, they all look something like this:

127.0.0.1 localhost
192.168.0.100 server
192.168.0.101 client_1
192.168.0.102 client_2

I'm moving these computers to a Windows network, where their IP
addresses look like this:

192.168.1.1 pc_A
192.168.1.2 pc_B
192.168.1.3 pc_C

So on the Solaris 10 x86 systems, I revised the /etc/hosts file of
those systems to look something like this:

127.0.0.1 localhost
192.168.1.100 server
192.168.1.101 client_1
192.168.1.102 client_2

Then, I rebooted these Solaris systems, but I no longer see them boot
up to the log-in screen like before.

Anyone knows what I did wrong? Please advise.

That would have worked if your systems had been configured properly in the
first place.

Execute sys-unconfig and when the systems reboot you will be prompted for
all the necessary configuration information.

I believe you need to edit more files than /etc/hosts.

As someone else said, sys-unconfig will do this for you. If you read the
sys-unconfig man page, it will tell you what files get edited, so you
could do it manually. But it is probably easier to just run sys-unconfig.
