1. Using Openstack Application credentials (EWC - OpenStack Command-Line client), identify your OLD LDAP machine 

   Code Block
   openstack server list

2. Detach the interface from the OLD LDAP machine (SERVER_NAME is the name of the VM from previous command, IP_ADDRESS is the private IP of the OLD LDAP VM, you listed with the previous command, SAVE IT in your notes and don't lose it!)

   Code Block
   openstack server remove fixed ip SERVER_NAME IP_ADDRESS

3. SSH In the NEW LDAP machine,
   1. Update the IP of the NEW LDAP machine in the /etc/hosts (IP_ADDRESS ) with the IP of the OLD LDAP machine ( The one you saved before in your notes!)

      Code Block
      [murdaca@ipa ~]$ cat /etc/hosts <!-- BEGIN ANSIBLE MANAGED BLOCK --> IP_ADDRESS ipa.batchpro.ewc <!-- END ANSIBLE MANAGED BLOCK -->

   2. Delete OLD LDAP machine DNS records (SERVER is the old LDAP machine complete domain (e.g. ldap-test-rocky.eumetsat.sandbox.ewc)
      

      Code Block
      ipa-replica-manage del SERVER --force

   3. Find the dns zone name 

      Code Block
      ipa dnszone-find

      
      

   4. Replace the NEW LDAP machine IP with the IP of the interface of the OLD LDAP machine (HOSTED_ZONE is the output name from the previous command, IP_ADDRESS=The one you saved before in your notes!, HOSTNAME is the new LDAP machine complete domain (e.g. ldap-test-rocky.eumetsat.sandbox.ewc)
      

      Code Block
      ipa dnsrecord-mod HOSTED_ZONE ipa-ca --a-rec IP_ADDRESS ipa dnsrecord-mod HOSTED_ZONE HOSTNAME --a-rec IP_ADDRESS

4. Switch off the NEW LDAP machine (SERVER_NAME is the name of the VM, you can find it with openstack server list )

   Code Block
   openstack server stop SERVER_NAME

5. Detach the interface from the NEW LDAP machine (SERVER_NAME is the name of the VM, IP_ADDRESS is the private IP of the NEW LDAP VM )

   Code Block
   openstack server remove fixed ip SERVER_NAME IP_ADDRESS

6. Add interface to the NEW LDAP machine with the IP of the old LDAP machine (SERVER_NAME is the name of the VM, IP_ADDRESS=The one you saved before in your notes!

   Code Block
   openstack server add fixed ip SERVER_NAME IP_ADDRESS

7. Add LDAP security group to new LDAP machine
8. Restart NEW LDAP machine (SERVER_NAME is the name of the VM)

   Code Block
   openstack server restart SERVER_NAME

9. Go to Morpheus and change the value in Cypher: Delete the secret/ldap_hostname and recreate secret/ldap_hostname it to point to the new ipa host (e.g. ldap.eumetsat.sandbox.ewc)
