Thank you for the prompt reply, that's a shame. I was hoping it would be straight forward without loss of any data or anything.
Hope you have a good weekend
To be clear...
There is no "permanent" loss of data.
Content/data being synced with iCloud and linked to your Apple ID will be removed when you sign out, as is expected.
Then when your wife signs in, her iCloud data will be synced again. If you use Apple Music or iTunes Match, that iCloud Music sync will need to be done again.
And repeat as needed. If there are a lot of music and photos, that could take some time and bandwidth.
iPhones are not ideal suited for shared usage. Again, it can be done, but I'll suggest it's like driving in screws with a hammer.
You'll get there but the experience may not be great.
