Using jusqu'à with perfect or imperfect past

[Emily Fields]

Hi,

This is the phrase I'm talking about:

Jusqu’à l’âge de quatre ans, j’ai habité en Allemagne.

In this context, would it be correct to use the past perfect tense because of the 'jusqu'à' or would I still use the imperfect (as in j'habitais)?

Please reply if you know which tense I should use!

Thanks
