When a new version of CWMS is released, HEC asks offices to upgrade their servers. Some offices may prefer to run the servers for the new version (under the 'cwt' application account) in parallel with the prior version (running under the 'cwp' application account).

Other offices will choose to switch their version running under the "cwp" account to the new version.  In this situation: 

  1. Log into your server as the 'cwp' user or 'cwt' user (if you are using test account)

  2. StopCWMS (if wish to be thorough can follow-up with 'ps -ef | grep java' and verify no CWMS processes remain)

  3. cd /wm/yyy/localsoft (where 'yyy' is your 3-letter District code)

  4. remove existing cwms link
  5. rm cwms
  6. ln -sf /wm/wmsoft/cwms/v3.3.1.231127 cwms (or whatever version of cwms you want to update to)
  7. BootCWMS
  8. checkServers 


Ensure that everyone in your office also updates their client software. It can be downloaded from several locations described in the release announcement. The client is also included with the server software inside the WindowsClient subfolder.
