AIX How to exchange hostname and IP address between two AIX servers?

Hi all,

I am trying to exchange hostname and IP address of two AIX machines.

But i am confused as how to change it ?
do i need to use "smitty mktcpip" or "smitty tcpip" ?

what is the difference between smitty mktcpip and smitty tcpip ?

Also anymore steps to follow or just updating using smitty is enough (hoping that no reboot is required)

Also below is the procedure i want to use for the whole process of swapping hostname and IP address:

1) remove server A from network and update hostname and IP address (to Server B's hostname and IP) using smitty

2) move network connection cables from server B to server A

3) update hostname and IP of server B (to that of server A's old values)

4) attach network cables removed from server A to server B

Does this procedure is good to go ?

Thanks in advance!

ipa-replica-prepare(1)						 IPA Manual Pages					    ipa-replica-prepare(1)

NAME
ipa-replica-prepare - Create an IPA replica file SYNOPSIS
ipa-replica-prepare [OPTION]... hostname DESCRIPTION
Generates a replica file that may be used with ipa-replica-install to create a replica of an IPA server. A replica can only be created on an IPA server installed with ipa-server-install (the first server). You must provide the fully-qualified hostname of the machine you want to install the replica on and a host-specific replica_file will be created. It is host-specific because SSL server certificates are generated as part of the process and they are specific to a particular hostname. If IPA manages the DNS for your domain, you should either use the --ip-address option or add the forward and reverse records manually using IPA plugins. Once the file has been created it will be named replica-hostname. This file can then be moved across the network to the target machine and a new IPA replica setup by running ipa-replica-install replica-hostname. A replica should only be installed on the same or higher version of IPA on the remote system. OPTIONS
--dirsrv_pkcs12=FILE PKCS#12 file containing the Directory Server SSL Certificate and Private Key --http_pkcs12=FILE PKCS#12 file containing the Apache Server SSL Certificate and Private Key --dirsrv_pin=DIRSRV_PIN The password of the Directory Server PKCS#12 file --http_pin=HTTP_PIN The password of the Apache Server PKCS#12 file -p DM_PASSWORD, --password=DM_PASSWORD Directory Manager (existing master) password --ip-address=IP_ADDRESS IP address of the replica server. If you provide this option, the A and PTR records will be added to the DNS. --reverse-zone=REVERSE_ZONE The reverse DNS zone to use --no-reverse Do not create reverse DNS zone --ca=CA_FILE Location of CA PKCS#12 file, default /root/cacert.p12 --debug Prints info log messages to the output EXIT STATUS
0 if the command was successful 1 if an error occurred IPA
