Ansible conditional betwen variables - ansible

Question

I have to check whether source and target are not the same directories and if they are not to change the name:
#Renaming bamboo-home folder
- name: Get {{ bamboo_home_symlink }} symlink target
stat:
path: "{{ bamboo_home_symlink }}"
register: symlinkhome_target
tags:
- upgrade
- name: change name of folder to be {{ bamboo_home }}
shell: mv '{{ symlinkhome_target.stat.lnk_source }}' '{{ bamboo_home }}'
when: symlinkhome_target.stat.lnk_source is not {{ bamboo_home }}
tags:
- upgrade
Unfortunately I have got following error:
19:02:31 TASK [change name of folder to be /usr/data/atlassian/bamboo-8.1.2-home] *******

symlinkhome_target is defined. See result of stat:
19:02:31 "stat": {
19:02:31 "exists": true,
19:02:31 "gid": 0,
19:02:31 "gr_name": "root",

The warning tells you what you are doing wrong that causes the error message.
19:02:31 [WARNING]: conditional statements should not include jinja2 templating
19:02:31 delimiters such as {{ }} or {% %}.
Additionally, you should be testing for equality (!=) not identity (is not).
- name: change name of folder to be {{ bamboo_home }}
shell: mv '{{ symlinkhome_target.stat.lnk_source }}' '{{ bamboo_home }}'
when: symlinkhome_target.stat.lnk_source != bamboo_home
