@saurabh shekhadar Out of curiosity, why do you need to use EnergyPlus v7.0? That release is from over 9 years ago and lots of features have been added or changed over that time.

You can still download E+ v7.0 from energyplus.net, which should contain the example files. Regarding your v9.0 models, could you just change the version number to 7.0 and see what happens? The simulation will probably fail, but E+ v7.0 should report what's wrong with the model. Then you can check the IDD definitions to "correct" your model manually. Here is an IDD browser you can use: https://app.ensims.com/idd.html

Of course, if you have a complex model or many of them, this will not be a good idea.

And be sure to compare the results files between the V7 model and original V9 model to verify they are not wildly different, which would point to other version differences that need to be addressed.
