#### [ CLI ]
**AWS CLI**
**Reemplazar un perfil de instancia de IAM para una instancia**
En este ejemplo, se reemplaza el perfil de instancia de IAM, representado por la asociación `iip-assoc-060bae234aac2e7fa`, con el perfil de instancia de IAM denominado `AdminRole`.
```
aws ec2 replace-iam-instance-profile-association \
--iam-instance-profile Name=AdminRole \
--association-id iip-assoc-060bae234aac2e7fa
```
Salida:
```
{
"IamInstanceProfileAssociation": {
"InstanceId": "i-087711ddaf98f9489",
"State": "associating",
"AssociationId": "iip-assoc-0b215292fab192820",
