Renaming Existing Deployment App

[arrangineni]

I need to rename the existing deployment App which is being actively used by a client and is sending the data to the Indexers. Can I simply change the rename the App from the deployment server and and redeploy to the client? Do I need to make any other changes within the App to override the old App name? More particularly will that try to re-index the data again?

Any inputs will be helpful

hi @arrangineni,
If the the only thing changing is the name of the deployment app, this is how to do with minimum (almost zero) disruption.

1.) On the DS, clone the old app directory cp /oldApp /newApp
2.) Update the app name in newApp/*/app.conf (if specified - should be in default, but could be in local)
3.) Add newApp to the existing serverclass and reload the Serverclass
--- this will push the duplicate app to your UF - depending on its name it may take priority over the old one immediately. (n comes before o etc.)
4.) Give time for your forwarders to download and restart with the new app.
5.) remove oldApp from serverclass and reload.
6.) Old app is removed, leaving newApp in its place.
7.) remove oldApp from DS
