# Modifying a profile
<a name="modifying-a-profile"></a>

You can't modify a AWS Elemental Conductor Live profile after it has been created. This rule ensures the dependability of profiles: a channel that uses profile\$1A and that was run two weeks ago has the same profile data as a channel that uses profile\$1A that was run yesterday.

If you want to modify a profile so that you do not have to recreate it from scratch, take the following steps.

**To modify a profile**

1. Duplicate the profile. Change values as desired and then save the profile.

1. Take the appropriate action:
   + If you duplicated the profile in order to fix errors in a profile you only just created, delete the incorrect profile.
   + If you duplicated a profile that is being used by one or more channels, remember to associate the channels with the new profile. Then delete the unused profile. 
     + To change the association for only one channel, see [Modifying a channel](modifying-a-channel.md).
     + To change the association for several channels that use this profile, see [Changing the profile used by multiple channels](changing-the-profile-used-by-multiple-channels.md).
