Hi, We are using a new Datacenter and have to move the data from old cluster to new cluster. Cluster Old New HDFS 2.7.1.2.3 3.1.1.3.1 Hbase 1.1.2.2.3.2.0 2.0.0.3.1 Zookeeper 3.4.6.2.3 3.4.9.3.1 OS Debian 7 (Wheezy) Debian 9 (Stretch) Since the major versions are different, I only know of one option for data migration: CopyTable. (+ SyncTable) Are there any challenges to keep note of, since we have different OS. Is there a way to online replicate the data? We have around 40 tables and around 1TB of data for each. How many copy table operations can be run parallel? Thank you
