This was a short night because of the final of the world championship and the celebration afterwards. Germany made it !
There are still many VSE systems on unsupported releases. Some are even on VSE/ESA 2.3, which had an end of service of 2001.
Customers may decide to migrate to the latest System z processors and upgrade to a supported z/VSE release afterwards.
Or they are on processors prior to z9. In that case you need to migrate to a new processor, before the upgrade to z/VSE Version 5.
z/VSE Version 5 only supports z9 or higher. ... and after October 2014 (z/VSE 4.3 end of service) z/VSE Version 5 is the only supported environement.
You need to prepare the VSE system on your current system, before you migrate to a new processor. Please consider, that the z114 and z196 processors are the last ones that support ESCON attachments. zEC12 and zBC12 do not support ESCON. If you still want to use ESCON attachments with zBC12 / zEC12 you need a FICON/ESCON converter.
For VSE/ESA 2.2, 2.3 and 2.4 you need to apply patches before the migration, otherwise those systems will not IPL on the latest processors.
Please contact me or use our contact web page to get the patches. The VSE/ESA system as well as the patches remain unsupported.
VSE/ESA 2.5 and later should have the latest service level applied. VSE/ESA 2.5 and 2.6 need at least APARs DY45944 and DY45958.
Please also consider the following:
The capacity of the new system is capable of covering your workload.
You may need to contact your vendors (e.g. for new license keys).
Be also aware that new devices are not tested with out-of-service releases.
It might be necessary to install a supported z/VSE release (+ required PTFs for OSA/SF) to configure the OSA-Express cards. If your target processor is a zBC12 / zEC12, you can configure the OSA-Express4S and OSA-Express5S cards via the HMC (Hardware Management Console).
