# Stop QuickBuild server of previous version, you do not need to stop agents since they will be auto-upgraded after server is upgraded.
# Extract installation package of new version to a new directory.
# Open a command line window, and switch to the _bin_ sub directory under the *new version*'s installation directory. Run command _migrate.(bat|sh) <install directory of previous QuickBuild version>_ to migrate from previous QuickBuild version.
# For windows platform, NT service will be installed automatically for the new QuickBuild server if old QuickBuild server is configured to run as NT service. However the new service runs with local system account initially and the "interact with desktop" option is disabled. You will need to change this manually after migration if necessary.
# Start QuickBuild server in new installation directory and agents will be auto-updated.
# Some build and user agents may not get started automatically after upgrade. You may check inactive node list from grid page and start them manually by logging to the machine with appropriate users and running command _<agent install dir>/agent.(sh|bat) start_. This only happens when upgrading QB4 to QB5 as 5.0 introduces the bootstrap upgrading mechanism but unfortunately cause the agent to stop for the first upgrade. After this start, the agent will be able to update and start automatically when upgrade to new versions even if the bootstrap libraries are changed.
