How to downgrade - From 4.5b6 to 4.4

Featured Replies

 

Hello everybody!

 

I have a problem with my server and I want to check that it isn't a software problem. So, firstly I want to downgrade from 4.5b6 to 4.4.

 

Just to point out, I have a Plus license.

 

So, to do the downgrade, Do I just have to change the following files? :

 

bzimage

bzroot

 

Nothing else?

 

Thank you so much.

It is that easy.

You can rename the existing two files so you can put them back into place as bzroot and bzimage if the experiment does not result in an improvement.  I do that on my system.  bzroot would become bzroot.456 and bzimage woud be re-named as bzimage.456

 

As an alternative, you could add the 4.4.2 files as bzroot.442 and bzimage.442 and then add three lines to your syslinux.cfg file.  They would result in additional menu choices when you next boot to allow you to choose to boot on either the older or the current version.

 

A copy of my syslinux.cfg file is below.  You can see I can elect to boot on on almost any of the recent releases, as I've kept re-named copies of each release in turn on my flash drive.

(All the lines I added are in "blue", the three lines for 4.4.2 you would need to add are in "bold blue.".  It would require you to put the 4.4.2 files in place renamed as bzroot.442 and bzimage.442)

 

The only thing you need to be aware of if you re-name the files as I've done is the names must be legal names under DOS on a FAT file-system.  Therefore, the names must be at most 8 characters long with a three character "extension"

bzimage.456 is legal, bzimage.45b6 is not. (because it has a 4 character extension)
