Upgrade from 1.x to latest version

Hi all,

I need to upgrade from 1.x to latest version of hadoop. Can any one of you help me how to do that. do i need to take any backup before upgrading the cluster. Is it possible to upgrade directly from current version to recent version or not. we are using hortonworks.

Thanks in advance.

Since you are using Hortonworks… Can you tell me which version of HDP and Ambari are you using currently? And for which version of HDP and Ambari you are planning for?

we are using 1.7 version of HDP now. Planning to move to 2.5.0
