Migrate from Centos7 to Rocky 8

Creating a new LDAP to migrate to

Switch IP interfaces between LDAP

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

   Code Block
   openstack server list

2. SSH to the VM with Openstack client installed and run the following commands:
   1. Show information about the OLD LDAP machine (SERVER_NAME usually is ldap in the tenancies by default):
      

      Code Block
      openstack server show SERVER_NAME

3. 1. Detach the interface from the OLD LDAP machine (SERVER_NAME is the name of the OLD LDAP 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
   1. !)

      Code Block
      openstack server remove fixed ip SERVER_NAME IP_ADDRESS

4. SSH In the NEW LDAP machine ,(LDAP replica)
   1. Update the IP of the NEW LDAP machine in the /etc/hosts (IP_ADDRESS ) with the IP of the OLD LDAP machine and remove the line relative to the OLD LDAP ( 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 name:

      1.  You can find this information loggning in Morpheus → Tools → Cypher and check the following secret → secret/ldap_domain

      2. 
         

         Use ipa command

         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

5. SSH to the VM with Openstack client installed and run the following commands:
   1. 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

   2. 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

   3. 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

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

      Code Block
      openstack server add security group SERVER_NAME ldap

   5. Restart NEW LDAP machine (SERVER_NAME is the name of the new LDAP VM)

      Code Block
      openstack server restart SERVER_NAME

6. Go Login to Morpheus and change the value in of the hostname for LDAP, going to Tools → Cypher:
   1. Delete the secret/ldap_hostname
   and recreate
   1. Image Added
      
   2. Use the '+ADD' to create a new secretImage Added
   3.  Add KEY: secret/ldap_hostname
   it to point to the new ipa host
   1. and VALUE: new LDAP hostname (e.g. ldap.eumetsat.sandbox.ewc) Image Added
      

Tests

1. login with DNS from ssh to ssh-proxy
2. ssh using DNS to the new LDAP machine
3. Run sudo ipactl status → verify the services are all up and running
4. Deploy From Morpheus go to Provisioning → Instances and deploy a new machine and enrollto test the enrolment to LDAP DNS is working correctly.

Post Installation (optional in case of similar errors)
