Possibility of upgrading from RHEL5 to 6 without affecting the data.


Hello Guys,
I have a server currently running on Red Hat Enterprise Linux Server release 5.9 (Tikanga). I would like to upgrade it to version 6, but I want to maintain all the data in the server. I have 2 VGs, using ext3.

How can I do the upgrade without affecting the existing data on both VGs?

Can I upgrade and do a restoration? Do I need to convert ext3 to ext4 for all the VGs? If yes, should I convert it before or after the restoration and what is the safest way to do it?

Thank you in advance.

Red Hat documentation says you shouldn't so you best don't. Best way forward IMHO would be to set up a new RHEL 6.4 server with the same VG specs then migrate data between hosts.

Also contact redhat tech support
They have tools for moving data from older databases to the newer versions

red hat has ZERO support for inplace rhel5 to 6 "upgrades"
as in they DO NOT SUPPORT IT
and that will null and void any support contract


install RHEL6.4 on a new server , then migrate over the data ( with red hat support's help )

Hello,
Thanks all for the replies. I'll proceed to backup and restore the fs to the new upgraded system. I've contacted RH support earlier and their replies are not very helpful, e.g.:

- A backup and restore would be advisable in your case.
- This would be a file level backup and restore so the the impact would only be how reliable your backup medium is

With all due respect it's just that you lack the knowledge and experience to be able to interpret them as such. These remarks actually are helpful and display nothing but common sense.

As you can see, I posted this question under Linux newbie thread, which means yes i lack the knowledge and experience, when i said RH support was not being very helpful it is because they gave me general answers and a URL which of course are not very helpful for a newbie like me, which is why I chose this forum to seek advice. For you to make your own interpretation on why I made that remarks is not helping me in any way to understand the solution to my problem. Looks like people in this forum expect you to have a certain level of skills when posting questions which I think does not serve the purpose of this "Linux newbie thread".

well you will have to do a new install using RHEL 6.4
on a new server
then upgrade the games that are on the game servers and databases
those upgrades may or may not be able to have the data ported to the new versions ?
-- we do not know --
Red hat tech support should be able to help with that

it is very likely to take a bit of time to port all the games on the servers over to 6.4

some of the old software ( that runs on the old 5.9 ) might run on 6.4 , but they should be upgraded or rebuilt from source


without knowing what is running on them ........
there is no way to tell .


a few years back when i moved from CentOS 5.6 to centos 6.1
i rebuilt every program i built on the old os .
it depends on what it is
some data will move over just fine
some will not
for some programs the program changed a LOT in a few years and there is no way to use the old data on the new program
