I currently have the 2013 MP it is
6 core 3.5, 64 gigs ( OWC mem )
Dual D700s
512 ssd

I am rocking the original OS 10.10.5 ( I am one to only update an OS when I am experiencing a given issue )

As I have grown more and more annoyed by well honestly lots of things I have very reluctantly made the decision to install Mojave.

I didn't really think this through it appears as I need to do an intermediate upgrade to 10.13 first??

This is problematic for many reasons. First my intent was to pull the current system drive AFTER a backup and then Hard archive the drive as it exists. I am a bit of a disaster media wise as I am a professional photographer and honestly the ONE freaking area my OCD doesn't rule me is in my Data storage "system" it is a cluster eff. SO to that end I am nervous even though I will have the backup I create I worry IF i end up in a situation where I hit a wall and have longer down time than a day I will have issues, at least if the drive is in its current state I can use it in an emergency and have the software ( LR specifically as allllll my client shoots are there )

SO my question for you all is this

First and I am hoping against all hope here, is there a way for me to flash whatever is needed to be flashed to accept the new drive on the Logic board , according to OWC that is gonna be where I run into issues?

IF there is no way to do that can I possibly install 10.13.whatever to an external bootable drive and then use THAT drive to install to the NME drive ? ( I really don't see why not? )

any other suggestions are very much welcomed. I feel a bit silly as I spent nearly 15 years building custom PCs when Jumpers dip and DAcs and SCSI were the way to make hardware play nice lol but here I am now feeling feeble :)

I have scoured Google, and the Youtubes for this and got Nada tons of info on installing to "non compliant" but not this although I do wonder if just treating it as a non compliant install may work?

I try to always do as pristine an install as I can so I would prefer to not be taking multiple runs at this .

Thank you all for the time , Be well

To be clear the new drive is blank is 1 tb and is the correct form factor :) Purchased from OWC
 
MP6,1 BootROM upgrades only happen when the original Apple SSD is present internally, there's no known circumvent for this. We still don't know why, if Apple uses this as a protection/security measure, or if it's needed for a bootstrap, or failsafe, whatever.

The problem is, you will need to keep it present in the GPU slot every time Apple sends a new Mac Pro firmware upgrade. This year Apple upgraded the BootROM 6 times already (127.0.0.0.0, 128.0.0.0.0, 129.0.0.0.0, 130.0.0.0.0, 131.0.0.0.0, 132.0.0.0.0) between betas and general release. Don't matter if you use High Sierra or Mojave, both have firmware upgrades with new point releases or Security Updates.

No, it won't work as an external drive for upgrades, only internally. You will have to re-install the Apple SSD internally every time there is a new BootROM. You can defer updating, but you will need to do it at some point in time.

Interesting I have upgraded the old SSD to Mojo. but still feel a clean install is the way to go. I am unsure if I will try using the OWC drive or not ,

Does it need to be the original or an original Apple SSD? i.e. Mine originally came with a 256GB but I've replaced it with a 1TB Apple SSD but in the Amfaltec AngleShark Carrier board with a couple of Samsung 970 Evos. I'm stuck on 127.0.0.0.0 with 10.15 beta 6 and I assume this might be due to the carrier board? I guess I'll have to rip out the carrier board next time there's an update and give it a go.

Any Apple OEM SSD, connected directly to the GPU SSD connector.

Thanks. As I suspected. Would I be missing much in the mean time? Did a lot change do you know? Not much info around it seems.
Apple don't publicly publish change logs, but it's microcode corrections and a lot of security improvements.
