Important settings overwritten by upgrade

[GerryHickman]

old : PCP_VERSION=6.0.5
new : PCP_VERSION=6.2.0
While upgrading form RHEL 9.3 to RHEL 9.4
/etc/pcp.conf saved as /etc/pcp.conf.rpmsave
but that means my settings have been overwritten
PCP_ARCHIVE_VERSION has reverted from "3" to "2"
PCP_ARCHIVE_DIR has reverted back to default '/var/log'
