Light fixture chain
You can check at local home centers for light fixture chain or with local lighting shops in order to extend the chain. If you can not find a matching chain for extension, you may need to purchase new chain. Too, you may need to splice wiring to extend to meet new location. Most of the light fixture hooks have wing nuts on them. You will need to remove the old hook, push any exposed hardware up into hole in ceiling, and plug. Purchase new hook. You can easily relocate the fixture. You should not have to move wiring.
