XenServer 7 was published on May 24, last month. It is a phenomenal release, some major new product enhancements, the XenApp and XenDesktop help customers derive increased value from their Citrix investment.
Inevitably, though some older XenServer Versions are at the end of their coming supports life, and as I know that some customers even these product versions use remain, I would like to draw attention to the publications here.
The Matrix Citrix Product Lifecycle covers all data and from the XenServer Table I 'd want to draw your attention to XenServer Versions 6.0, 6.0.2 and 6.1, all of which are to go through end-of-life ( EOL) next September.
XenServer 6.0 & 6.0.2 are already in Plant Maintenance (EOM), and I honestly hope XenServer admins already have updated to a newer version of this infrastructure, as it is currently it is not a technical support. For XenServer 6.1 infrastructures maintainability data already on the original intention extended is good, and while there are still a few months Support links, version 6.1 go at the end September 2016 EOM & EOL !
With the above product lifecycle dates in mind when using XenServer versions prior to 6.2, you should be aware at this time of license structure changes. These older versions per-host-based licenses used, the socket licenses per CPU changed in XenServer 6.2, matching the market trend of hypervisor and additional product licensing at the time.
with need to upgrade customers even per-host-based licensing these licenses through their Citrix their account portal. License upgrades are subject to active Software Assurance (SA) and exchanged on a 1: 2 basis (for each host license, you get two CPU socket licenses). As part of the license swap, you must agree to the older Pro-host licenses to withdraw, but customers can still use their host licenses during the XenServer resource pool upgrades, they once this process is complete abolition.
from a product edition perspective, all XenServer 6.1 licenses introduced (regardless of Edition) roll up in XenServer 6.2 and with active software maintenance (SWM Citrix XenServer 6.2 as an alternative SA and 24 × 7 technical support to separate) can then upgrade 6.5 / 7 Enterprise Edition XenServer. There is no license swap outs needed from XenServer 6.2 to 6.5 or 7, as the 6.2-licensing will be easily recognized by the license server as applicable for Enterprise Edition against any 6,5 or 7 infrastructure.
This includes XenServer Licensing and key product lifecycle data that must be taken into account for some upgrades. What is the best process the host upgrades for the conclusion? Well, why not blog in its own right in the future. There are a few technical considerations to take into account, based on the provision, the criticality of workloads, and is an issue on which there are many opinions!
If your XenServer infrastructure is near the end of its support reached, reach for advice on how best to your local authorized Citrix partners to continue.
