Over the last few months, I’ve been dry running our migration from NS7 to NS8. After working through a few issues with help on this forum, I feel like I finally have a handle on all the pieces that I will need to put in place (including NethSecurity) for the migration. So I re-installed the target NS8 OS and Nethserver. I then went to connect the NS7 migration tool to the NS8 cluster and I get the following:
Error connecting to NS8: Task has failed: ('error': '<3>add-node failed. Worker version 0.0.0 must be compatible with 3.9.0.\n', 'exit_code': 3, 'file': 'task/cluster/a5b9fadd-815e-440e-9fb0-367f7d3f5925', 'output': [('error': 'core_version_mismatch', 'field': 'core_version', 'leader_version': '3.9.0', 'parameter': 'core_version', 'value': '0.0.0')])
I’ve never had a problem with this step during my dry runs, and I didn’t find anything on the forum related to “Worker version” mismatch. Any guidance would be greatly appreciated.
I installed the NS7 migration tool a while ago. The NS8 is a fresh install today. If I uninstall the NS7 migration tool, will I be able to reinstall it even though NS7 is no longer available/supported?
The packages/updates are still provided for NS7 so you could just go to NS7 Software Center and update.
It’s also possible to uninstall and reinstall the migration-tool.
So I uninstalled the NS8 Migration tool from my NS7 server, and nothing shows up in my Software Center to be able to reinstall. Do I have to do it manually?
