When I try to install Mojave, I get an error message saying that "This volume is not a supported Core Storage configuration". I had to replace the hard drive on my iMac with an SSD drive. How do I upgrade to Mohave? Is Apple aware of this issue, which many others seems to also be having?

First of all do a full clone of your drive to an external drive, using SuperDuper or CCC. Also have an up to date Time Machine backup.
Make sure your can boot from the clone and works correctly.
Download the Mojave installer (in this case apparently you already have it) and follow the available instructions to create a bootable installer on a thumb drive.
Boot from this thumb drive, erase your internal SSD and install.
You can choose at this point to migrate your user accounts from the clone or do it later by running Migration Assistant from your new Mojave system.

FWIW, as I tried explaining on the first page, the Mojave installer does not "like" Samsung EVO drives.
I have Mojave running on single-disk Macs with EVOs without any issues. The issue is the Mojave installer, which is confused with two SSDs.

Interesting, as I mentioned previously others have posted they couldn't get Mojave to install on their EVOs and I don't believe they had two. Also others had trouble if they had a third-party replacement drive other than EVOs.
I can only go by what I've read. What I can't remember is if the problems were limited to Mojave but also occurred with High Sierra.
Just a thought.
Good to know. If someone had issues with single-disk EVOs, perhaps I can take a look and see if their issues can be resolved. I have MBPs (13-in and 15-in) with 2.5-in SATA drives where EVOs replaced old Apple HDDs.
Hi Luis
I have done all the steps you suggested, up and including erasing the internal SSD. When I try to install macOS Mojave from the thumb drive to the "Macintosh HD" internal SSD, it gives me the error message "This volume is not a supported Core Storage configuration". It was deleted using the Mac OS Extended (Journaled) format.
What do I need to do next to install the OS please?

Do I delete the drive and then restore from TM?
Backup your macOS installation using the current TM setup as you have it now.

Also, am I sharing too much detail with the volume numbers?
The CS LV/LVG UUIDs are generated every time it is rebuilt, so there is no 'private' information. The Partition Type GUIDs are standard and publicly documented, so there is no 'private' information in these either.

How do I go about rebuilding the fusion drive?
Once the backup is complete, post a text version of
diskutil cs list
which will allow me to copy/paste UUIDs for the commands to be used to rebuild the CS LV/LVG.

It was looking so good. The Macintosh HD volume came up and I started installing the Mojave OS to it. The little line on the screen went across almost twice and then stalled at the grey screen (for over 10 minutes now). Should I force a shutdown with the on/off button at the back?
Interesting, as I mentioned previously others have posted they couldn't get Mojave to install on their EVOs and I don't believe they had two. Also others had trouble if they had a third-party replacement drive other than EVOs.

I suppose it could be specific models assuming they have them, with differing firmware. This is beyond my experience. I've never had to replace an internal drive. The most I've had to do is re-fuse a Fusion drive 6 years ago. 😎
My hero!
I am sure it is running faster with the new system and/or the new drive configuration. I have restarted it twice and it has behaved both times.
Thank you so much for all of your calm help and patience - and staying with the task until it was fixed. Hopefully others can learn from this fix. All the very best to you.
Excellent. Please backup Mojave via Time Machine, before you start installing additional software. If you see any issues with Mojave, please post back. We have chosen larger reserve sizes for some of the partitions to avoid issues in the future. Thanks for being persistent.
Do you plan to install Windows? If yes, report any issues you have.
For future readers, can you post the text output of

No, I don't plan to install Windows. The 'diskutil list' and 'diskutil apfs' outputs follow.

Is this a Samsung EVO drive by any chance?
It is a Samsung SSD 850 EVO 1TB installed with an Apple SSD controller SD0128F.
Can't upgrade to Mojave on iMac with SSD
