Hello MQ Fans!

MQ 7.1 introduces a very transcendental feature which has many implications for installation, administration and runtime: it is possible to have multiple versions of MQ installed in the same machine. This was not possible with MQ 7.0 and previous versions. Even though you may want to have only one version of MQ in the machine, such as 7.1, the MQ developers wanted to ensure that you could have the freedom and flexibility to install another version to coexist in the same machine, such as 7.5.

I wrote 3 techdocs that provide very specific scenarios: the first one is a straight upgrade from MQ 7.0 to MQ 7.5 (no coexisting) in Linux, and the other 2 are for coexisting MQ 7.0 and MQ 7.5 in Linux and in Windows. Please keep in mind that most of the chapters in the techdocs for Linux apply also to AIX, HP-UX and Solaris, and that only the first chapters (actual installation instructions via rpm) are only applicable to Linux.

• Upgrading WebSphere MQ 7.0.1 to MQ 7.5 in Linux
  This technote is a straight upgrade and does not exploit the 'multi-version' feature introduced with MQ 7.1, in which several versions of MQ can co-exist ("side-by-side"). You can upgrade from MQ 7.0 to MQ 7.5, without first going through MQ 7.1. MQ 7.5 also includes Advanced Messaging Security (AMS) and Managed File Transfer. This document does not cover their installation. The scope is only for the MQ Server, MQ Explorer, JMS and Development toolkit.
  
  
• Installing WebSphere MQ 7.5 to coexist with MQ 7.0.1 and MQ 7.1 in Linux
  This techdoc shows all the steps to install WebSphere MQ 7.5 in Linux, while co-existing ("side-by-side") with MQ 7.0.1 and MQ 7.1. MQ 7.5 also includes Advanced Messaging Security (AMS) and Managed File Transfer. This document does NOT cover their installation. The scope is only for the MQ Server, MQ Explorer, JMS, Development toolkit and GSKit. The minimum version of MQ 7.0 that allows coexistence is 7.0.1.6. Because at the time of writing this techdoc the latest Fix Pack was 7.0.1.9, then 7.0.1.9 is used in this document. The "primary" installation will be MQ 7.0.1.9 and this techdoc shows you how to setup the environment in order to use MQ 7.0, MQ 7.1 and MQ 7.5. The overall instructions apply also to other UNIX® distributions: AIX, HP-UX and Solaris.
  
  
• Installing WebSphere MQ 7.5 to coexist with MQ 7.0.1 and MQ 7.1 in Windows
  This technote builds on top of the document entitled "Installing WebSphere MQ 7.1 to coexist with MQ 7.0.1.7 in Windows + applying fix pack 7.1.0.1". MQ 7.5 includes also Advanced Messaging Security (AMS) and Managed File Transfer. This document does NOT cover their installation. The scope is only for the MQ Server, MQ Explorer, JMS, Development toolkit and GSKit. The minimum version of MQ 7.0 that allows coexistence is 7.0.1.6. Because, at the time of writing this techdoc, the latest Fix Pack was 7.0.1.9, then 7.0.1.9 is used in this document. The "primary" installation will be MQ 7.0.1.9 and this techdoc shows you how to setup the environment in order to use MQ 7.0, MQ 7.1, and MQ 7.5.

Thanks!
