-Then run Configure.
+If you wish to use your old config.sh, be especially attentive to the
+version and architecture-specific questions and answers.  For example,
+the default directory for architecture-dependent library modules
+includes the version name.  By default, Configure will reuse your old
+name (e.g. /opt/perl/lib/i86pc-solaris/5.003) even if you're running
+Configure for a different version, e.g. 5.004.  Yes, Configure should
+probably check and correct for this, but it doesn't, presently.
+Similarly, if you used a shared libperl.so (see below) with version
+numbers, you will probably want to adjust them as well.
+
+Also, be careful to check your architecture name.  Some Linux systems
+call themselves i486, while others use i586.  If you pick up a
+precompiled binary, it might not use the same name.
+
+In short, if you wish to use your old config.sh, I recommend running
+Configure interactively rather than blindly accepting the defaults.
