Remember that things can go wrong – and indeed!
Before you go mad, gently warn in the wind and start improving, be aware that there are risks. Things can go wrong, things can break, and you can lose data. Many iOS launches have been hampered by bugs and issues, so it's a good idea to make a recent backup by not giving up your photos or documents.  You can either create a local backup using iTunes or a backup in iCloud by going to Settings > iCloud > Backup and then turn on. iCloud Backup .
Remember that if you're not ready to jump through hoops and do things that Apple disapproves of, making it an easy journey to iOS 11.3, you might want to get other people to go ahead just in case there are problems.
You ignore backups at your own risk!
How good is the latest version of iOS 11.3?
Hmm. I'm always of the opinion that I have to comment on the beta code because it's a beta code after all. That said, with the upcoming release of iOS 11.3, the latest beta release will give us some pointers on what the final release will look like.
And right now, the latest beta feels shaky at best. While the release feels pretty good in terms of stability, performance-related things do not feel very good. I see lags and frame drops regularly on a variety of devices, and overall responsiveness leaves much to be desired. At the moment, it's hard to say if this is due to diagnostic and debugging code in the iOS beta or a major performance issue affecting the final release.
Spring clean your iPhone or iPad
Presumably your iPhone or iPad has amassed a lot of detritus over the months and years, so what better time to get rid of it now.
While iOS 11.3 does not consume as much free space as some of the previous versions of iOS, it makes sense to get rid of apps that you no longer use – or perhaps never used.
Know Your Passwords
After the upgrade, you'll need to enter your iCloud password to be able to reconnect to all your data and photos. If you do not have it near you – remember that it's not so comfortable on the device you are upgrading on – then this might be a good time.

If your iTunes backup is encrypted, then remember that you need this password if something goes wrong!
If you're still using iOS 10, get ready for the "Appocalypse"
The end is close to all 32-bit iOS apps. So, if you have not already upgraded to iOS 11 and still rely on older apps, it's time to find alternatives.
For some time now, Apple has warned iPhone and iPad users that older 32-bit apps could slow down their devices, but with the recent release of iOS 10.3, Apple has escalated things by making it clear that this End is near.
Apps for compatibility with the built-in Checker tool (you need to run iOS 10.3 or higher for this to work, but no t iOS 11!).
See: Settings > General > About > Applications .  From there, you'll get a list of all 32-bit apps on your iPhone or iPad that can not run on iOS 11.3. If you're lucky, no apps will be listed, or the apps listed are old stuff that you forgot that you have installed and are no longer using.
However, if an app you rely on is listed, then you must prepare for its demise.
Is it better to update or delete the device and start over?
It's much easier to update a device than keep all your apps and settings.
Devices that I've deleted and reloaded a new iOS device and then installed and set up all my apps feel faster and seem to have fewer issues (such as Bluetooth and Wi-Fi). problems). However, wiping and reloading the apps and data is quite tedious and probably more work than most companies would like.
Should I wait a bit before upgrading?
There will probably be an update or two on iOS 11.3 in the weeks following the release, so you should wait for the dust to settle and all last-minute bugs to be squeezed before you make the leap, especially when you rely on your device.
If you do not like to handle bugs, it may be wise to hold back for a few days. If you want to be on the loose, destroy the update button as soon as Apple releases iOS 11.3 (but do not say I did not warn you!).
If you're using your device in a BYOD setting, make sure you get the OK from IT before the upgrade if you can not access the network or data you need.
