Welcome back to the forum.
Can I remind you that your real name appears to be showing in the forum, if you want to change this then follow the instructions in the following FAQ
My full name is showing, how can I stop it?
In principle, you can appeal the ESA Decision but whether there is any value in your doing so will depend on when the Decision was made, what it involved and whether an existing award was in place?
Once you make a claim for UC you cannot return to ESA even if the appeal is successful, also, you would also have to be assessed for Limited Capability for Work under the UC claim and the resulting Decision will supersede any revised ESA Decision limiting the time that the revised Decision would apply for.
