iOS 11 – Geting Ready

Every year I do a version of this post for family and friends. So, here it is.

iOS on your iPad is going to radically alter the way it works. Be prepared for this. If you use your iPad for any form or productive work then consider holding off until you know all of your apps are compatible, and you’ve got time to establish your workflows.

iOS includes two new image and video formats. Things will be easier if you are running the latest OS on everything.

Another big feature of iOS is imessages in the cloud. As above – things will be easier if you are running the latest iOS on everything.

Read this if you are upgrading your device
iOS is normally released 1 week before the new iPhones. Within that time there is normally a point update (11.01).
Due to the way that backups work you can restore an older backup onto a newer version of hte operating system. You can not restore a newer version of a backup over an older version of iOS.

iPhones will normally ship with the first major release (11.0). So if you take your exsiting device to 11.01, back it up, then try and restore onto your new device you will have to wait for the new version to install. Several million people may be doing the same thing at the same time.

With any software upgrade it is always worth waiting a day or two to allow any significant problems to be discovered and fixed. You may also avoid problems if the authorisation and activation servers get hit.

Apple uses two different processes – authorisation and activation.

Authorisation is to ensure that the downloaded iOS update is valid. This is done for security reasons, and to stop people reverting back to previous versions. 

Activation is sometimes done to link an iTunes account with the iphone, and to validate certain carrier information.

If authorisation fails you will not be able to install iOS 7.

If activation fails you will not be able to use your phone.

To put things in context – iOS 5 in 2011 caused BT to report its biggest ever traffic spike – and there were far fewer iPhones about then.


Pre planning planning
Install the latest version of iTunes. While you don’t need iTunes to install iOS 11, you will need it if things go wrong.


Make sure you know the passwords for any e-mail accounts and other services that you have apps for on your iPhone. It will be easier to try and get these back if you have some details of the account used.

if you have any authenticator apps on your phone, ensure that you have suitable backups / recovery keys for all of the accounts covered.


App pruning
If the upgrade goes well then you don’t need to worry about reinstalling apps. If things don’t go well and you have to restore from backup then the number of apps you have installed will increase the time taken to do a restore.

When iOS restores data it restores the user data, and then downloads the app from the app store (or syncs across from iTunes).

All apps that are non essential should be deleted, and any others which may be linked with an account but not carry data e.g club card apps, financial apps, etc. Ideally you should also delete the apps before you do your final backup.

Any app that has its own data that isn’t synced to a server anywhere should be kept.

Make sure that your ios device has backed up successfully.

Make sure your iPhone is fully charged and plugged in.


More Patience
Allow an evening for this. Do not start the upgrade at 6pm if you need to leave the house at 8.


Your device should be ready to go with shiny iOS 11 goodness. There will be a few weird bugs. If you didn’t want these, then you should have waited ;).
