copycluster doesn't work between two different Vertica DB versions (6.1 & 7.2)

elmahdyh

Hello All,

 

I want to migrate the Vertica database of onenode from one machine with older version (vertica-6.1.3-0.x86_64 to) to another machine with a newer version (vertica-7.2.0-1.x86_64) using the copycluster task by vbr.py

 

I got the following error when running the vbr.py script:

File "/opt/vertica/bin/vbr.py", line 576, in getAddress
if hostname.find('localhost') != -1:
AttributeError: 'NoneType' object has no attribute 'find'

 

 

I think this error is because of the two databases have different versions.

 

My question is:
*******************

Is it possible to do this migration using the copycluster task between the two different Vertica DB versions or I should upgrade the older DB first , then do the migration (copycluster) ??

 

Thanks in advance.

Best Regards

You have to first upgrade old db to the same version as the target cluster. Copycluster is not supported across these versions.
