Upgrading a slightly out of date Ionic 3 application

Ionic Framework ionic-v3
1

My ionic info output for our Ionic 3 application is currently:

Ionic:

   ionic (Ionic CLI)  : 4.1.2 
   Ionic Framework    : ionic-angular 3.9.2
   @ionic/app-scripts : 3.2.3

Cordova:

   cordova (Cordova CLI) : 8.0.0
   Cordova Platforms     : android 7.1.4, ios 5.0.0
   Cordova Plugins       : cordova-plugin-ionic-keyboard 2.1.2, (and 21 other plugins)

System:

   ios-deploy : 2.0.0
   ios-sim    : 7.0.0
   NodeJS     : v8.12.0 
   npm        : 6.4.1
   OS         : macOS
   Xcode      : Xcode 10.2 Build version 10E125

We will eventually be migrating the application to Ionic 4 but in the meantime I’d like to update this project to use the latest packages etc.

It appears the following upgrades are available:

Ionic CLI to 5.4.2
Ionic Framework to 3.9.9
Ionic App Scripts to 3.2.4
Cordova to 9.0.0
Cordova Android to 8.10
Cordova iOS to 5.0.1.

Does anyone have any advice as to whether these upgrades would be reasonably safe or whether I am likely to run into any issues? Thanks.
