OC200 Controller Migration to Software Controller Error
I am trying to migrate from an OC200 controller to a new software controller running in a docker container.
OC200 is on 5.12.9
The new software controller is on v5.12.7
If I migrate the site from the OC200 to the new software controller this completes successfully but this does not restore all the existing client names. (i have exported the client names from the OC200 but there is no way to import these into the new controller).
If i use the controller migration feature I get a failure to restore on the new software controller. The restore on the new controller gives a 'Failed unknown errror try again later' message in the UI.
I have tried numourous backups, settings only, 30 days, 60 days, with and wothout user data. All fail to restore on the new software controller. A manual backup and restore also give the same error.
Can anyone point to the issue? Thanks.
The following error is in the logs.
