Apple Disk Recovery Assistent

I bought a MacBookPro back in October 2012 with OS X Mountain Lion (as far as I remember). My mac is currently running on OS X Yosemite. I am planning on changing the hard drive to a bigger one and will back up my data with time machine. I have read that I need to install the apple disk recovery assistent (I only found the one for OS X Lion and have downloaded that?) and then reboot my mac with that. I hope this makes sense so far. Now my question is. If I reboot my mac with the OS X Lion recovery assistent and then back up my mac with my time machine that has my current OS X Yosemite on it, will this cause any issues?

I hope someone can help. Thank you.

What model MBP?

I get that you’re trying to use Disk Recovery Assistant to format a new drive and then restore a Time Machine backup of your Yosemite volume to this new drive using this:

OS X Recovery Disk Assistant v1.0

I think your best option is Internet Recovery, which is built into the firmware of all Macs sold since 2012 and can be loaded via an EFI update for Macs built since 2010 that didn't come with it.  It will pull up the latest version of the tools and should be backwards compatible.  You could install your new drive, start up with Internet Recovery, use it to format your drive, and then restore your Time Machine backup to your new drive.

There are other means that I think are more convenient.  I’ll explain in a separate post.

Recovery Disk Assistant was a stopgap item issued to cover a perceived problem. It was released when downloaded software was just beginning. Its need has since evaporated, and it was never updated.

It is NOT a mainstream tool, and you should NOT be relying on it.

The most trouble-free way to upgrade to a new drive is to place it temporarily in an External enclosure. Then the full power of the old drive, as well as the full capacity of the new drive can be applied at once. Install mac OS on the new drive from scratch, and (if you have confidence in either your old drive or its backup) use either to bring in your Account data and User-Installed Applications at initial setup, using Setup Assistant.

[Users whose old drives are questionable may need to use the new drive and its software to perform some Data Rescue operations before proceeding.]

Then when you have complete confidence that it is working properly externally, perform the "surgery" to place it inside your Mac to regain portability.

The Big Advantage of this method is that you are installing a "known good", properly working drive with working software. Any problems that develop are directly attributable to the "surgery" or the Internal drive cable, and are quickly debugged and easily dealt with.
