Currently we have LR 7.51 with us, which includes Controller, Generator and 50 VU license.
Now we want to purchase LR 7.6 which will include Load generator and 200 VU license.
My questions are,
1. Can we run script in LR controller 7.51 which is developed in Load generator 7.6?
2. Can we use VU’s which I have purchase with LR7.6 license on LR 7.51
If you are under maintenance with Mercury you should be able to request your copy of 7.6 (if it has not already been sent to you).
I work in an environment where scripts are being developed in LR VUGEN 7.51 and 7.6 and the controller version is 7.51. Make sure that you don't make use of any new 7.6 functions or you loose a degree of portability between versions. The more critical factor is that all of your load generators and controller be at the same release/patch level prior to your test execution.
Have we run into issues? Not yet. I say "yet" because what we are doing is likely not officially supported with the mix of release levels. So apply your mixed levels of release at your own risk.
