Lightroom CC: Very very slow migration from Lightroom Classic

Since 3 weeks I'm trying to migrate my LR Classic catalog to LR CC on my iMac. I have 80'000 photos at around 800GB. The catalog migration of the first 40000 photos went at reasonable speed within 1 day - but since the last 3 weeks it has only migrated additonal 17000 photos. And this is only migrating the catalog. Uploading the photos to the cloud is even slower - only around 3500 photos have been uploaded to the cloud during the migration process.
I have stopped and restarted the migration process a couple of times by closing LR, but without improvement.
I'm considerably frustrated about this migration and really need help before I trash all this.

What is the free space on the disk where your default Pictures folder is located?

I found the root cause of the problem: I stored my photos on my NAS and that slowed down the process dramatically. I moved all photos to a local attached HD and re-started the migration process. The migration completed after one day and the sync of all photos was completed after 3-4 days.
So finally a success of the migration.

Now I realise a different problem:
All photos are migrated, but not all photos are associated to their corresponding album in the web/iOS version. Some albums are empty, others only contain a subset of the photos they should contain. In LR CC Desktop on my Mac everything is correct.

Is there anyway how I can reforce a sync of the album association to the cloud or any other efficient way of re-assigning the photos to their albums?

Hi, I just want to confirm that it seems that the sync issue has now been resolved with the latest version of LR CC - released yesterday (i.e. 20190502-0902-47ed471).

It has not been resolved for me. My lightroom migration is extremely slow. I'm getting averaging about 1-2% a day.

I am having a similar issue. My migration is painstakingly slow, about 1-2% a day. I cannot see how many photos have been transfered, only the percent complete. My LR Classic and LR CC have both been updated to recent versions.

Have you got enough space for all the photos on the target drive Michael? I'm wondering if it's running out of space and having to wait to upload photos before it can carry on. Or is the originals storage on a NAS, as that's been reported with some performance issues. Which operating system?
