NO. Please don't do this. Please don't take this as best practice moving forward with MQ 7.1 and 7.5.
USE SETMQENV or SETMQINST.

mqjeff, I did a MQ v7.1 installation on AIX 6.1. I tried to set primary installation with the following command and it failed.
setmqinst -n Installation1 -i
So as you said I tried setmqenv -s and still after that, the above command fails 
Please let me know if you need any information |

Did you try it as root?

I wanted to confirm this. We have the below scenario.
1) We had MQ 7.0.1.12 version and few queue managers on this.
2) We installed MQ 7.5.0.4, along with this, using the multi-stage approach
3) That makes MQ 7.5.0.4 as secondary installation (Installation1) and MQ 7.0.1.12 as primary(Installation0).
4) We have created few new Queue mgrs on MQ 7.5.0.4 and also migrated the older queue managers from 7.0.1.12 and they are working fine now.
5) The Product manual suggests the sequence as per which
a) uninstall MQ 7.0.1.12 and
b) then make the MQ 7.5.0.4 as primary.
http://www-01.ibm.com/support/knowledgecenter/SSFKSJ_7.5.0/com.ibm.mq.mig.doc/q006660_.htm
6) However we want to make MQ 7.5.0.4 as primary first and ensure it all works and then only uninstall MQ 7.0.1.12
We get the below error when we try to make the MQ 7.5.0.4.
AMQ8579: Primary installation cannot be changed from 'Installation0' to
'Installation1'. If the current primary installation is Installation0, it is not possible to set 'Installation1' to be the primary installation until Installation0 has been uninstalled.
There was a suggestion in the error log to first unset the primary installation.
"Otherwise, in order to set installation 'Installation1' as the primary
installation you must first unset the current primary installation using the
command 'setmqinst -x -n <InstName>'. You can then re-issue the command to set
installation 'Installation1' as the primary installation. "
We tried to first unset the current primary installation using the
command 'setmqinst -x -n <InstName>'> But it did not work and gave this error.
Installation 'Installation0'(C:\Program Files (x86)\IBM\WebSphere MQ) is
implicitly primary.
The command attempted to modify the primary installation 'Installation0',
however this installation is implicitly primary and can only be made
non-primary by uninstalling this installation.
Is it mandatory that the older version of MQ 7.0.1.12 has to be uninstalled before we make 7.5.0.4 as primary? |

It categorically states within the 7.1 and 7.5 KCs that, "...WebSphere MQ version 7.0.1 is automatically the primary installation. You cannot select another installation as the primary installation while WebSphere MQ version 7.0.1 is installed...", or did you miss that when you read the Installing and Uninstalling sections?

Yes. v7.0.n is (as the command says) implicitly primary because that version doesn't support co-existence. So in software design terms it's the only installed version and therefore the primary by virtue of it being the only version. Thus no command can make it not primary; the only way to make it not primary is to uninstall it.
As the command text attempts to make clear.

It's a good plan, and for future migrations it will work great. Right now, you just need to take a deep breath and pull the Band-Aid off....

If you have multiple MQ installations in your system. Here is the procedure to unset and set the Insttallations.
First, Unset the previous version of your MQ7.1 Installation with the following command
SETMQINST -x -n <Installation name>
Then close the cmd and open it again and Now set as primary installation for your MQ7.5 as primary with the below command
SETMQINST -i n <Installation name>
Close the Cmd prompt and You can able to access your MQ7.5 as primary Installation and can work on it.
If you still having any issues. Please let me know i can do that.
