Hi Team, We wrote YAML scripts under the version 1.5.3 and 2.1.1 (virtual environment). Now, we would like to move to either ansible-2.4 or ansible-2.5 So, what is the way to migrate my code to latest version ? Or do i need write the complete code from scratch ? Can anyone please suggest me on this ? Thanks & Regards Devaraju Gedela ---

The answers are in the Porting guides. [https://docs.ansible.com/ansible/latest/porting\_guides/](https://docs.ansible.com/ansible/latest/porting_guides/) Cheers,   -vlado ---

Usualy compatibility is quite good... When going from 1.9 to 2.1, I had quite some porting code to do From now, change between version is generally deprecated before being obsoleted. So expect some work for your very old scripts using version 1.5... Regards, ---

Hi Devaraju, It’s best to upgrade to a maintained version. We maintain 3 versions at all times - currently those versions are 2.9, 2.8, and 2.7 - see [https://docs.ansible.com/ansible/latest/reference\_appendices/release\_and\_maintenance.html](https://docs.ansible.com/ansible/latest/reference_appendices/release_and_maintenance.html). We do not fix bugs in unmaintained versions, so if security vulnerabilities exist in version 2.4 or 2.5, they will not be fixed. Best wishes, Alicia ---

Thanks Alicia for letting us know about maintained versions. But, While i’m upgrading my scripts from 1.5.3/2.1.1 to 2.9 , Some of the expressions were not getting evaluated successfully. I found that “%{%d:%Y:%H:%m:%S}t” is not getting evaluated and throwing the error like “ERROR! failed at splitting arguments, either an unbalanced jinja2 block or quotes” Finally, {%{%d} is not getting evaluated in ansible2.9 bit i’m not sure in rest of the maintained versions. Could you please help me on this ? ---
