Can i use this command on my VPS-9 ?
Is this a soft upgradation command which remains all my custom programs and settings, or convert into fresh copy with zero updates.
my basic Running programs are in
/etc
/var
/usr
is this all directories still remains or all OS back to fresh?

I mean network speed, disk speed, or what else?

Normally a fresh install of an OS should run faster than the previous one you have used for some period of time.

Mashiro Wrote:Warning: Debian might be generally a very stable OS but distribution upgrades are something that can be rated as dangerous and should be handled with care. I don't recommend to dist upgrade a long running server with applications and other things already running on it. Even if you decide to do so take backups! Things could go wrong and the server could be rendered unusable! Therefore I would like to explain that I'm not responsible for any damage that might happen to any server when performing a distribution upgrade. I recommend only to do this on a fresh installed Debian 9 VPS where you have nothing to lose!

Mashiro Wrote:@hamed @sagher

Have you both ignored the red text that is placed at almost the top of the tutorial post?

It answers your questions pretty much in terms of if you should do this or not and when you should do it or not.

About the question by @hamed: During the upgrade the packages are upgraded and the kernel. Of course partially configurations are replaced with newer versions that come with the new software. However for everything you changed or custom configured you will be asked mostly if you wish to replace the configuration or keep the original. And for the most it will NOT replace any configuration during an upgrade. So nothing is mixed up. You are still just upgrading the packages to the level the newer Debian version.

https://post4vps.com/Thread-Easy-way-to-upgrade-Debian-9-to-Debian-10

To say the speed increased, is understating it.  Debian 8 performance was OK and normal fast.  But after the reboot, the performance of my VPS was like lightning in comparison.  How come?

They are not that complete and can put one on the wrong path very easily, particularly if one takes them seriously.

Based on @Mashiro's input in Post#4, I would say that the jump from a 3.16.x (in Debian 8) to a 4.19.x kernel (in Debian 10) should not go unnoticed while everything else being equal.

(05-29-2021, 08:48 AM)deanhills Wrote: But yes, I've worked through MANY tutorials on the Web for step by step LAMP + WP from places like rosehosting.com and equivalent, and I think those are tutorials that have been written as "bait" to get traffic and to subscribe to their managed accounts services.  Like more often than not the tutorials are part of SEO.  So inevitably they miss out on finer details like step by step for creating directory trees, config files etc.  I'm glad that I stumbled through them, even though it was a great waste of time, as I then got to appreciate the gaps in their tutorials when I worked through Mashiro's tutorials in the end.  It was a good learning curve overall.
