Hi guys
I was wondering is there some smart way to migrate Solr cloud from 1 set
of machines to another?
Specificaly, I have 2 cores, each of them with 2 replicas and 2 shards,
spread across 4 machines.
We bought new HW and are in a process of moving to new 4 machines.
What are my options?
1) - Create new cluster on new set of machines.
- stop write operations
- copy data directories from old machines to new machines
- start solrs on new machines
2) - expand number of replicas from 2 to 4
- add new solr nodes to cloud
- wait for resync
- stop old solr nodes
- shrink number of replicas from 4 back to 2
Is there any other path to achieve this?
I'm leaning towards no1, because I don't feel too comfortable with doing
all those changes explained in no2 ...
Ideas?
