Hi, I have 2 exising nodes running datastax community 1.0.10. I want to add 2 more nodes and I assume the best practice would be for those to be the same version. However, I could not find any older versions available. Is it ok to add the new nodes as 1.1 versions and then upgrade the older nodes? I noticed there are some hector client incompatibilities between 1.0.x and 1.1. I guess I will need to upgrade the clients and point them at only the new nodes, then upgrade the old nodes, and then finally update the clients to access all nodes?

adding new nodes with newer versions?(3 posts) (3 voices)
There is a big different between 1.0.x and 1.1 unfortunately (e.g. in schema migrations) so I would recommend you to first upgrade the old nodes and only after that set up the new ones.
