[D] What’s the best way to move CS4.19 from CentOS to Ubuntu [cloudstack]
GitHub user nxsbi created a discussion: What’s the best way to move CS4.19 from CentOS to Ubuntu
Hello all,
little background- I currently have 4.19 on CentOS 7. I want to move advantage of 4.20.
Per documentation, I would need to move to RedHat/Oracle/Rocky Linux 8.
I had bad experience with Rocky Linux 8 just last month where a fresh install and then yum/dnf update to kernel causes grub confuse to get deleted. Many issues like this posted on Rocky Linux forums… so do not want to use that.
so I plan to move to Ubuntu instead (mainly because for the stable support and development). What’s the best approach to moving to Ubuntu and upgrade to 4.20 as well?
my thought is below:
- setup 4.19 on new Ubuntu server
- Point this management server to existing sql database so it’s a second management server using the same metadata
- Shutdown original management server
- Upgrade Ubuntu based 4.19 to 4.20
- move the mysql server to this server by backup restore and update the db.properties file.
are these the right steps? Is there any documentation around this?
I am not sure how to handle
- usage server - do I set it up on second server as well and then shutdown the original? Will I lose any data? (Cannot lose data)
- How do I transfer the existing 2FA so existing users do not need to setup 2FA again.?
Any direction would be helpful.

Hello all,

Per documentation, I would need to move to RedHat/Oracle/Rocky Linux 8.
I had bad experience with Rocky Linux 8 just last month where a fresh install and then yum/dnf update to kernel caused Grub config to get wiped (there are many such posts so not a user error). Any how- so I plan to move to Ubuntu instead (mainly because for the stable releases and my prior experience). So my question is What’s the best approach to moving to Ubuntu and upgrade to 4.20 as well?
my thought is below:
- setup 4.19 on new Ubuntu server
- Point this management server to existing sql database so it’s a second management server using the same metadata
- Shutdown original management server
- Upgrade Ubuntu based 4.19 to 4.20
- optionally move the mysql server to this server as I am using single management server setup by backup restore and update the db.properties file IP.
are these the right steps? Is there any documentation around this?
Additionally, I am not sure how to handle:
- usage server - do I set it up on second server as well and then shutdown the original? Will I lose any data? (Cannot lose data)
- How do I transfer the existing 2FA so existing users do not need to setup 2FA again.?
- Any additional steps for Console ssl besides the standard ones?
Any direction would be helpful.

:D ubuntu?!? (/me kidding)
your steps look fine (testing advised)
- about the usage server, just stop it while no job is running and restart it at your convenience on any other host.
- the 2fa depends solely on the url used in your solution, if it was a proxy address it should still work (am I correct @harikrishna-patnala ?)
- the console ssl might need re-provisioning of certificates, but I wouldn’t expect that. You should check https://cloudstack-documentation.readthedocs.io/en/latest/adminguide/systemvm.html#using-a-ssl-certificate-for-the-console-proxy to make sure the configuration is still valid.
