I have to downgrade the php version of a bitnami ubuntu image to support some legacy codes. I tried to look for different methods that suggest using apt-get and dpkg to remove the 5.4 and install 5.3 of php version. However those steps don't work because the bitnami image doesn't have php installed through apt-get or dpkg.
Is there any other way that I should try to downgrade this server to have php v 5.3?
