Red Hat upgrades?

I'm going to test upgrading one of my production Virtual Machines. The
VM is running RHEL4. Can I go from 4 to 6? Or do I need to upgrade to
5 before 6?

I think you're looking at a clean install.

cd command and auto complete

Friends:

I use bash.  Take this scenario

prompt>ls -l
config
configevents

prompt>cd co<TAB>

It does not alternate between config and confievents folder(s)

However on Windoze platform

c:\users\narahari>dir
config
configevents

c:\users\narahari>cd co<TAB>
It presents both config first and then another <TAB> puts configevents.

How can I get that behaviour in bash ?

That is not acceptable.

So far as I know RHEL doesn't have an upgrade path between major
releases.  You can upgrade RHEL5.4 to RHEL5.6 simply by doing "yum
update" but I don't know of a method to go from RHEL5.6 to RHEL6.0
without doing a reinstall.

Based on experience years ago with a well planned upgrade between major
releases of a commercial UNIX I decided it was never worth the effort
because:
1)  There is always something you didn't plan for.
2)  Much cruft behind from the old release that you're never quite sure
it is safe to remove.
It is much simpler to do a fresh install (ideally to a new machine) and
migrate applications over.   The other benefit to this is there is a
clean backout (i.e. using the old server) if the new environment has
issues.

Re: Pentium vs AMD vs DDR3 based motherboard

Well I am slowly taking a bite towards the DDR3.  I am getting

MSI ATX mother board + AMD proc for $108

Memory 8GB is 55.(I can get 4GB for 29)

So I am paying $155 (or 138)

If I go with DDR2 I approach I will be paying 65.(not for memory, which I have already but the new mother board)

Yes I have not considered a case but I can wait for that I guess.

My current processor is BE 2400(score of 1211) and my new processor will be the X4 840. (score of 3740)

Any good cases around for an ATX motherboard ?

Re: Red Hat upgrades?

By the way they changed the way subscriptions work in RHEL6.  I don't
know the details but you should probably investigate before you upgrade.

Re: Red Hat upgrades?

On rethinking it did seem to me that when I installed a RHEL6 system
there was an option for upgrade.

This page has screen shots showing it.

rhel-6-install-screenshots/

Haven't done it and won't for the reasons noted but if you want to
try...

Such a thing astonishes me. There are plenty of other, _free_,
distributions that have solved this problem. It makes no sense to me
that the premier paid distribution would be broken in this way.

It will _not_ be easier for me to upgrade in this manner. The design
of the application makes this prohibitive.

We already have new licenses. That's why I am considering this test.
