To not know how to get all my data from my iPhone to huawei phone?

[goodtimesahead]

I got my new huawei phone and there is an app called phone clone that you can use to take all contacts photos etc to your new phone I tried to do it and it didn't work.

A few of my photos have gone on but not all! What do I do? I'm not the best with technology but I'm not terrible it just seems tricky.

Also my whatsapp previous chat history did not come onto my new phone! Is it possible to do this from iPhone to android

Confused

Backup and sync everything you can to the cloud. Then, import it to your new phone. Google is pretty good for free cloud storage.

I did backup everything to iCloud

Then used the phone clone to transfer to my new phone and it only took a few photos

Is there another way to import it to my new phone?

I backed up my phone as a whole to my google drive, then re downloaded the profile and it installed it as a new profile on my huawei.

There is an app called Phone Clone I think from Huawei which does it?

I am now trying to back up to Google drive but it's taking forever! Phone clone wouldn't work as it's not compatible with iPhone

It's taking forever, I'm not sure if I have too many photos etc
