I have different calendars and different contacts on my iPhone and iMac (Mojave) (each device has unique data) and I want to merge/sync them . If I turn on iCloud for calendars and contacts on both devices, will I lose the unique data from one or the other device? Or will information from both devices merge and be loaded into iClould?
iPhone 6s, iOS 13
WaukJiM,
When you enable syncing for your contacts and calendars, you'll get prompted with the option to merge the items from your device with iCloud.
Set up iCloud Contacts
When you turn on iCloud Contacts, all of the information* stored on separate devices uploads to iCloud. If you turn off iCloud Contacts, your information won't automatically move from iCloud back to your device.
On your iPhone, iPad, or iPod touch
1. Go to Settings > [your name] > iCloud.
2. Turn on Contacts.
3. When you're asked if you want to Merge or Cancel, tap Merge.
All of the information stored in Contacts uploads to iCloud.
You can also find those details in this resource: Set up and use iCloud Contacts - Apple Support
Hopefully that addresses your inquiry.
Take care.

Hello WaukJiM,
It's important to know if the reason you have differing data on your two devices is because you have two different iCloud accounts?
This article shows where to go on each device to sign into iCloud, but the same steps can be used to see what iCloud account you're currently using on each device:
Sign in with your Apple ID - Apple Support
Best Regards.
WaukJiM,
That's a great question. When contacts, calendars, and reminders are in iCloud, iCloud automatically updates your information across your devices. The following article can help:
Set up iCloud for Calendar on all your devices
Thanks!
Have a great day.
Hi
I am have a single Apple ID.
So - If I turn on iCloud for calendars and contacts on both devices (same Apple ID), will I lose the unique data from one or the other device? Or will information from both devices merge and be loaded into iClould (and then be reflected on both devices?)
Thanks for you help.
Hi
But what happens when I first turn on iCloud on the two devices, both with different data (but with the same Apple ID) ?
Does the unique data from each device merge in Iclould or do I lose the data from one device or the other?
Thanks for trying to assist
Hi
Thanks for you reply - I am using a single Apple ID (the same on both devices).
Hello WaukJiM,
As long as the Apple IDs are different then the information will not merge. The information for each Apple ID will remain with that Apple ID.
Thanks!
