Let's say you have a SysV Init Script named foo

Copy the file to /etc/init.d/foo
Enable the SysV service: chkconfig --add foo
Enable the SysV service: chkconfig foo on
Start the service: service foo start. After this, systemd-sysv-generator will generate this file /run/systemd/generator.late/foo.service, copy this file to /etc/systemd/system by running: cp /run/systemd/generator.late/foo.service /etc/systemd/system/foo.service
Edit /etc/systemd/system/foo.service by running systemctl edit foo.service, add in the following line to foo.servie (this makes the service installable)
