The IBM Engineering Lifecycle Management applications provide different options of registering or reregistering applications in the common scenarios server rename, upgrades and installing a new application.
This document shows the advantages and disadvantages as well as the best practices for using the different options to avoid issues.

---++ Available options
---+++ repotools -setup (all applications in response file)
---++++ Advantages
   * The response file can be reused for different scenarios (new installation, server rename, installing additional application)

---++++ Disadvantages
   * Take the longest time as runs the setup (the setup rerun for all applications)
   * Fails if the setup fails at one of the steps even if this step is not necessary (e.g. can fail on ccm setup for server rename scenario)

---+++ repotools -setup (only one application in response file)
---++++ Advantages
   * Executes the setup only for applications which need this
   * Response file can be reused for particular scenario (e.g. we can create response file for server rename scenario for all servers)
   * Faster than repotools -setup with all parameters

---+++ repotools -registerApp command
---++++ Advantages
   * The simplest and the easiest command to run from server perspective
   * As executes only required stuff, it is the least error prone

---++++ Disadvantages
   * Does not provide password encryption for teamserver.properties
   * Not recommended for reregistering (cannot be used for server rename)

---++ Best practices
   * For new installation the only option is run repotools –setup with all applications in response file (option 1).
   * For reregistering LQE/LEX and other applications after server rename the recommended way is to put only these applications in response file (option 2).
   * For registering new applications added to CLM portfolio, like it was with /am recently, the recommended way is the third option.
