FC5 to FC7

[mnauta]

I'm running scalix 11.1 on FC5, can I upgrade to 11.2 while on FC5 and then latter upgrade it to FC7?

Thanks

I have the same question regarding suse 10.1 and suse 10.2

As Fedora and SuSE OSS are only supported as evaluation platforms, we only support one version at any one time. I would not recommend installing on an old version as the Scalix software is compiled on-platform, and thusly will be linked to the libraries on FC7/SuSE 10.2 respectively.

So it won't be a supported configuration to upgrade to 11.2 on a legacy platform.

when upgrading on a community platform, the only supported means is to re-install the OS, preserve /var/opt/scalix, then run a fresh new-install on the new system.

Florian - how about the enterprise edition? We are running FC5 on a xen box and we have the enterprise version of Scalix.

Do I still need to reinstall the OS, perserve /var/opt/scalix and then re-install?

Or do I need to do something else?

Thanks

I wasn't talking about community vs. enterprise scalix - they all behave the same w/respect to upgrades - it's the same bits, at the end of the day, different license key.

I was talking about not recommending to use Fedora or openSUSE for a production email system; these OSes change far too frequently for a server system. We do recommend going with RHEL or SLES for better long-term investment protection on the OS platform side.

That's why we officially only support Fedora and openSUSE for evaluation (i.e. short-term) use!

Thanks Florian - I understand now.

I will talk with the technology team and see if they want to go with RHEL or Fedora 7- either way its time to do something with the server.

Edit: Florian if we go with RHEL - will it be a problem when transferring /var/opt/scalix? Or will it work with no problems after the transfer?

Question on upgrading.

Right now the team decided to go ahead and do the upgrade to FC7 - our user base is small (60 users) so we decided to not go w/ RHEL.

Right now our server is configured as follows:

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
2.8G 2.1G 614M 78% /
/dev/xvda1 99M 30M 64M 32% /boot
/dev/sdb1 2.0G 84M 1.8G 5% /home
/dev/sdb8 2.0G 433M 1.5G 23% /var
/dev/sdb2 1008M 342M 616M 36% /var/log
/dev/sdb3 1008M 260M 698M 28% /opt
/dev/sdb4 40G 31G 9.3G 77% /var/opt/scalix
/dev/sdb9 40G 34G 6.8G 84% /backup
/dev/sdb6 1008M 34M 924M 4% /tmp
/dev/sdb7 4.0G 2.4G 1.5G 63% /usr
tmpfs 757M 0 757M 0% /dev/shm

This will be my first time installing Scalix - since our last email admin had already done this in the past.

I am going to do the install on another server so I do not have much down time. Do I just use the install guide under documents and then transfer over /var/opt/scalix?

When that is done and I decide to do the final migration - do I need to do anything else?

Thank you

[florian]

yes, doing a fresh install and copying /var/opt/scalix using some tool that preserves file ownership and permissions (extremely important) should do the trick.

you should also try to keep the hostname and IP address of the system, otherwise you're for hostname/ip-address changes - see the scalix wiki for detail.

Thanks Florian,

Yes the hostname/IP will stay the same when I do the final transfer. Thanks for your help.

Although V11.1 runs pretty darn well on FC5 (we have 225 users 100Gig /var/opt/scalix folder)

[florian]

Right - and there is *nothing* wrong with it - it's only that the upgrade schedule gets tough with having to do OS and Application at the same time - and we simply can't support/test more than one of their releases due to the amount of testing required and the frequency of new releases....

if you're happy with 11.1, you can run that on FC5 for ever!

I have done 4 upgrades from fedora core 5 to fedora 7 and all are working just as they were before. takes about an hour for each. be sure to remove the scalix db prior to upgrading to 11.2 the procedure is

1. upgrade fc5 to f7
2. stop scalix-tomcat ldapmapper scalix and scalix-postgres
3. remove the scalix db from the 11.2 installer (ie: select remove scalix components)
4. install scalix 11.2
5. reboot

[techsharp]

I think its best to do a fresh install as stated by Florian in the previous posts - and not to do just an upgrade.

[pharoh]

why?

we have been doing upgrades for years on servers. you just have to verify server operation on each upgrade. Yes there is a possibility that the upgrade could go ary. That is why we have a standard platform that we can test in house then create an upgrade procedure and roll out to customers.
