How to upgrade Apache Spark version

Question

Currently, I have installed Spark 1.5.0 version on AWS using spark-ec2.sh script.

Now, I want to upgrade my Spark version to 1.5.1. How do i do this? Is there any upgrade procedure or do i have to build it from scratch using the spark-ec2 script? In that case i will lose all my existing configuration.

Please Advise

Thanks

1.5.1 has identical configuration fields with the 1.5.0, I am not aware of any automation tools, but upgrade should be trivial. C/P $SPARK_HOME/conf should suffice. Back up the old files, nevertheless.
