Planning our upgrade to 5.0

[theRKF]

Currently running CentOS 6.6 with LiteSpeed 4.2.23 (installed by LiteSpeed staff) with cPanel and multiple versions of PHP.

We are eager to upgrade to 5.0, but I want to be sure our ducks are in a row.

Can someone please point me to the correct instructions for upgrading to 5.0?

Also, are there instructions available for rolling back to 4.x if we encounter problems with 5.0?

Many thanks!

The following two commands are what you are looking for:

/usr/local/lsws/admin/misc/lsup.sh -f -v <version>

/usr/local/lsws/admin/misc/mgr_ver.sh <version>

 

[theRKF]

Thank you!

To confirm: the lsup will move me to 5.0, and the mgr_ver will allow me to roll back to 4.2.23 if needed?

 

[NiteWave]

yes. but 5.0 still there but not running. so it's easier to switch between versions.

First attempt, mixed results:

LiteSpeed/5.0 Enterprise


Looks like the install didn't complete properly, but our hosted websites are still live and lsws is reporting 5.0 Enterprise running.

The web console is not working at all, just a blank page.

So, we're operational for the moment, but no ability to access the control console to configure anything.

 

[theRKF]

Re-ran lsup.sh and this time the install completed and the console is accessible.

The lsup will move me to 5.0, and the mgr_ver will allow me to roll back to 4.2.23 if needed???

Yes, that is correct.

By the way, I noticed that we need to run the upgrade command twice as it will throw up the error mentioned by @theRKF above when you run it for the first time.

@Pong @NiteWave You guys aware of this bug? We noticed it when we upgrade to 5.0 on a few test servers.

 

[Pong]

The error message is a glitch due to lsup.sh script itself being upgraded, so LSWS was not restarted properly.
If you switch to 5.0 now, it should work fine.

Thanks for the update. Will revert if I see this error again.
