+1. Increment the version of `SECRET_ENC_KEYS_B_VERSION=b1` to `b2`
+2. `abra app secret insert <app> enc_keys_b b2 "$(openssl rand -base64 32)"`
+2. Change `ENC_KEY_ACTIVE="a1"` to `b2` (this tells rauthy to encrypt new secrets with the new key while still having access to `a1`)
+3. `abra app deploy <app>`
+
+To rotate keys any future time, follow the same pattern of incrementing the non-active secret version and changing the active secret to that newly generated secret.

+WARNING! ⚠️
+This release supports encryption key rotation, which unfortunately requires some migration steps:
+
+1. Obtain your old encryption key (enc_keys) if you backed it up. If not, you can extract your current encryption key from the config file. This is pretty advanced and can only be done from the server itself:
+
+   docker secret list  # to obtain the secret's full name
+   docker service create --name temp-reader --secret <secret-name> --mode replicated-job alpine:latest sh -c "cat /run/secrets/<secret-name>" && docker service logs --raw temp-reader && echo && docker service rm temp-reader
+
+NOTE: the enc_keys secret has the format `<key_id>/<key_value>`; we'll refer to those two parts as $KEY_ID and $KEY_VALUE from here on.
+
+2. Add these lines to your config, overwriting the existing SECRET_ENC_KEYS_VERSION and ENC_KEY_ACTIVE values:
+
+    SECRET_ENC_KEYS_A_VERSION=$KEY_ID # generated=false
+    SECRET_ENC_KEYS_B_VERSION=b1 # generated=false
+    ENC_KEY_ACTIVE="$KEY_ID"
+
+3. Set key_a and generate key_b:
+
+    abra app secret insert $STACK_NAME enc_keys_a $KEY_ID "<your-existing-secret>" -C
+    abra app secret insert $STACK_NAME enc_keys_b b1 "$(openssl rand -base64 32)" -C
+
+Then you can deploy :)
