******************************************
Welcome to IOTA IRI Upgrade to 1.4.2.4_RC!
******************************************

What is this script going to do?

  1. Check the distribution (Ubuntu or CentOS)
  2. Check if you want to compile the jar yourself or download a precompiled one.
  3. Stop IRI
  4. Download or pre-compile the jar (which will install maven as it is a requirement)
  5. Copy the resulting jar to the target directory and create a symbolic link
  6. Configure the IRI configuration files (version and set RESCAN_DB = true).
  7. Restart IRI
  8. Remove the RESCAN_DB = true (it is needed once)

By pressing 'y' you agree to upgrade to 1.4.2.4_RC and keep the existing database.
In addition, note that this script will only work with installations done by
the iri-playbook.
