Trouble Migrating to C8 with cloud backup

[bertabcd1234]

Likely this:

[RESOLVED] Migration Failure from C-5 to C-8 [Platform version 2.3.6.146]

UPDATE 2: the fix has been released to the beta channel. If you'd like early access, please join the Beta Group . UPDATE: the issue has been identified and a fix will be released in the next update. We have seen an increased number of reports related to migration failure from C-5 hubs to C-8 using the latest platform version [2.3.6.146] . Our engineers are currently investigating. We kindly ask users to refrain from attempting to migrate from C-5 to C-8 until the investigation is completed…

Some users have had luck downgrading to 2.3.5 and trying again if you don't want to wait for the next platform release, where this will likely be fixed. To do that, assuming you don't already have 2.3.5 available in step 2:

1. Navigate to <yourHubIP>/hub/advanced/downloadPlatform/235 (and wait a few minutes for this download to complete)

2. Go to Settings > Diagnostic Tool (or just go to it directly at <yourHubIP>:8081), log in with your hub MAC as requested, select Restore Previous Version, and choose the latest (or only) 2.3.5 release available.
