iOS purchase

#1
Hello,
A few months ago I bought all the expansion packs for sfs on my iPad. They all worked fine. Now I have switched to a iPhone 7, but the Apple ID on my iPad no longer allows me to redownload apps so when I setup my new phone I was unable to download sfs. After realized this with not only sfs but many other apps I switched to a different Apple ID. Is there a way I can transfer my purchase? If you need a form of proof of purchase I can provide it. Thanks in advance!!!
