Thank you for your reply.
Currently, Bitnami 2.6.1 is used in Windows 2008.
However, the support deadline will end at 2020, so we are considering upgrading.
Can we use Bitnami 2.6.1 when OS is Windows 2012 or 2016?
We customized the application under PHP 5.4.36. so we are worried about whether the application will start normally when upgrading.
