Migrating from DHCPv6 1.001 to DHCPv6 2.001
This chapter discusses steps to migrate from DHCPv6 1.001 to DHCPv6 2.001 on an HP-UX
11i v1 or HP-UX 11i v2 operating system when you have configured your system as a DHCPv6
2.001 client, server, or relay agent.
NOTE Before migrating to DHCPv6 2.001, you may find it useful to read the sections
“What Is in This Version” on page 5 and “Removed Options” on page 11.
Migrating a DHCPv6 1.001 Server
If you have configured your system as a server or client using DHCPv6 1.001, complete the
following steps to migrate from DHCPv6 1.001 to DHCPv6 2.001 after installing the DHCPv6
2.001 software depot on your system:
Step 1. If you have configured IPv6 addresses for an interface using DHCPv6 1.001, you
must unconfigure IPv6 addresses using the ifconfig (1M) utility.
Step 2. Move the tags address-pool, subnet-prefix, and reserved-addresses from
the DHCP_POOL_GROUP section to the DHCP_ADDRESS_POOL section in the
/etc/dhcpv6tab configuration file. You can specify multiple
DHCP_ADDRESS_POOL settings for a single DHCP_POOL_GROUP.
For example, consider the following DHCPv6 1.001 pool group configuration in the
/etc/dhpv6tab configuration file:
DHCP_POOL_GROUP;\
pool-group-name = YELLOW;\
subnet-prefix = 5ffe:1234::34;\
prefix-length = 64;\
address-pool = 5ffe:1234::4321:1000 - 5ffe:1234::4321:9999;\
reserved-addresses = 5ffe:1234::4321:1222;
Following are the modified sections in DHCPv6 2.001 after moving the relevant
tags from the DHCP_POOL_GROUPS section to the DHCP_ADDRESS_POOL section in
the /etc/dhcpv6tab file:
DHCP_POOL_GROUP;\
pool-group-name = YELLOW;\
address-pool-names = APPLE;
