CentOS 6 is starting to feel really dated.

I'm considering moving my workstation to CentOS 7 while the rest of the network remains on 6.8, and becoming a guiena pig.

Can anyone point me to any material to help in a possible transition?

Any help would be appreciated.

Thank you everyone!

Greg,

 

Wow ok, I do support RV. Thank you for your anecdotes, yes Deadline is also included in our pipeline. Maybe it's time I create a spreadsheet!

... and I mention "redacted" becaus it appears nothing is off the table when it comes to what we do! =)

 

Thank you!!

redacted v3 and up will run fine on Centos7.

If you're using RV on Centos7, and artists start complaining about video playback, there are a few solutions in my other thread.

maya and nuke are both fine on cent7, not sure about redacted ;-) but have experience with deadline, redshift and several others, all good.

Gregs,

Thanks for the responses.

We use the usual DCCs (Maya, Nuke, <redacted>, <redacted>), but our shop is always testing and evaluating new software. At some points, I'm also developing and working with new packages that require a more recent kernel and everything else that comes with it. I think I spend more time in build hell than I actually do any work.

I'll point our team to this thread in hopes we can start a dialogue.

Thanks all, it's scary but I think we can manage it.

What applications are you using? 7 is definitely better than 6 once you drink the koolaid. My advice is not to fight it. At first we tried to ignore NetworkManager and get back to the device names we were used to. Don't do that. systemd is the same thing.

1. dd if=/dev/zero of=/dev/sda bs=512 count=10000
2. install centos 7

If your shop installs workstations via KickStart, there is an opportunity to reuse most of the 6.x KS. Many if not all the package names are the same.

took me a while to accpet systemd, more over nostalgic and 'it works for me' reasons than anything else. But it is a better system.

Yeah, no 6->7 upgrade path to speak of, you have to start from scratch. Even the default filesystem is different from 6 to 7, it is typically ext4 for RHEL/CentOS 6, and XFS for RHEL/CentOS 7. Read up on systemd and learn to accept it (there's probably a 12 step process for that), at first it will feel weird and wrong, but no use fighting it unless you plan to switch to a systemd-less distro...

Hi Alfred,

Unfortunately, there really aren't any 'migration' tools that I know of, if that's what you're looking for. Can't just yum update release to get to 7. At least that's what's been said on the CentOS forums. You could try adjusting the paths to the repositories, but I have a feeling that won't work out too well ;)

In terms of material, is there anything specific you're looking for? Trevor and the team on the CentOS forums are a great help if you run into any trouble. I'm using C7 (currently 1611, going to 1708 soon) as my daily driver and it's been fantastic. I think you'll like it!

Cheers,
Mike

Thanks Mike and Jean-Francois

I understand I'd probably have to start fresh, but maybe a set guide of things to look out for.

Python of course, major application issues, etc.

Thinking about this some more, I think the only way to really know what'll work (or not) is if I find a host machine I can tinker with.
