Hi all,
I am trying to upgrade an oVirt installation (3.6.7.5-1.el6) to 4.0. My datacenters and clusters have 3.5 compatibility settings.
I just finished this. Only took about 2 weeks for 8 hosts ;) I had to do this: 3.5 -> 3.6 - upgrade engine to 3.6 - create a new cluster with CL 3.6 - for each host: - maintenance - reinstall to el7 + RPMs (yay for puppet) - add to new 3.6 cluster - activate - migrate some machines to new cluster (no way back!) - elevate CL of old (empty) cluster to 3.6 - migrate everything back for each host 3.6 -> 4.0 - for each host: - maintenance - upgrade RPMS to 4.0 - activate - elevate CL to 4.0 (can be done with running VMs) -- Ernest Beinrohr, AXON PRO Ing <http://www.beinrohr.sk/ing.php>, RHCE <http://www.beinrohr.sk/rhce.php>, RHCVA <http://www.beinrohr.sk/rhce.php>, LPIC <http://www.beinrohr.sk/lpic.php>, VCA <http://www.beinrohr.sk/vca.php>, +421-2-62410360 +421-903-482603 --------------7BE1C0DAF9A990FF33D53A2A Content-Type: text/html; charset=windows-1252 Content-Transfer-Encoding: 8bit <html> <head> <meta content="text/html; charset=windows-1252" http-equiv="Content-Type"> </head> <body text="#000000" bgcolor="#FFFFFF"> <div class="moz-cite-prefix">On 23.09.2016 16:49, Bruckner, Simone wrote:<br> </div> <blockquote cite="mid:2CB4E8C8E00E594EA06D4AC427E429920F5AB077@fabamailserver.fabagl.fabasoft.com" type="cite"> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <meta name="Generator" content="Microsoft Word 15 (filtered medium)"> <style><!-- /* Font Definitions */ @font-face {font-family:"Cambria Math"; panose-1:2 4 5 3 5 4 6 3 2 4;} @font-face {font-family:Calibri; panose-1:2 15 5 2 2 2 4 3 2 4;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {margin:0cm; margin-bottom:.0001pt; font-size:11.0pt; font-family:"Calibri",sans-serif; mso-fareast-language:EN-US;} a:link, span.MsoHyperlink {mso-style-priority:99; color:#0563C1; text-decoration:underline;} a:visited, span.MsoHyperlinkFollowed {mso-style-priority:99; color:#954F72; text-decoration:underline;} p.msonormal0, li.msonormal0, div.msonormal0 {mso-style-name:msonormal; mso-margin-top-alt:auto; margin-right:0cm; mso-margin-bottom-alt:auto; margin-left:0cm; font-size:12.0pt; font-family:"Times New Roman",serif;} span.E-MailFormatvorlage18 {mso-style-type:personal-compose; font-family:"Calibri",sans-serif; color:windowtext;} .MsoChpDefault {mso-style-type:export-only; font-size:10.0pt;} @page WordSection1 {size:612.0pt 792.0pt; margin:70.85pt 70.85pt 2.0cm 70.85pt;} div.WordSection1 {page:WordSection1;} --></style><!--[if gte mso 9]><xml> <o:shapedefaults v:ext="edit" spidmax="1026" /> </xml><![endif]--><!--[if gte mso 9]><xml> <o:shapelayout v:ext="edit"> <o:idmap v:ext="edit" data="1" /> </o:shapelayout></xml><![endif]--> <div class="WordSection1"> <p class="MsoNormal">Hi all,<o:p></o:p></p> <p class="MsoNormal"><o:p> </o:p></p> <p class="MsoNormal"><span lang="EN-US"> I am trying to upgrade an oVirt installation (3.6.7.5-1.el6) to 4.0.
