I am contemplating upgrading my OS from Mojave to the latest Big Sur. I want to make sure I won't run into any trouble with my existing apps,( like Adobe Illustrator, Photoshop, Squarespace, Artwork Archive) once I upgrade?
iMac 21.5″ 4K, macOS 10.14
Tips How to Upgrade to Big Sur
There are several points to consider before attempting the upgrade to Big Sur. The most important is Due Diligence on the part of the User and is a Prerequisite for a smooth upgrade.
The below points should all be consider Before attempting the upgrade.
Point # 1 - Are there pre-existing Unresolved Software Issues. They should be resolved prior to upgrading - they may carryover to Big Sur making the system unstable / unusable.
Point # 2 - Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation. The Built-in Security of Big Sur is all that is required.
Point # 2 A - Commercial VPNs should only be used if Mandated by Corporate Head Office for working remotely. Otherwise - ones Privacy and Security touted by the VPN is suspect.
Point # 3 - What are the System Requirements ie: Empty Space Requirements specific to the Big Sur.
Point # 4 - Does the intended computer qualify for the upgrade.
Point # 5 - Are the installed Applications / Extensions compatible with Big Sur. Check with the Developer for compatible Apps / Extension or do they offer updates. Same goes for Third Party Drivers for Printer, Scanners etc.
Point # 6 - If upgrading from Mojave and earlier versions of macOS - Remember that Big Sur does not support anything 32 bit. These include Applications, Extensions and Drivers for any devices. There is no workaround.
Point # 7 - Do you have a Rescue Plan In-Place. This comprises having 3 Backups using 2 methods and 1 Off Site incase of Theft, Loss or Natural Disasters. A Time Machine Backup is very useful and can be used to Revert to Previous Working macOS. For addition purposes - two Tested Bootable Clones each to separate external drives. This is insurance incase the upgrades goes sideways. At least one Tested Clone and / or Time Machine Backup should be Off - Site
Point # 8 - To upgrade to Big Sur will requires a quick, stable and reliable Internet Connection - preferred method is via Ethernet Connection.
If not available and using Wifi - move computer as close to the Access Point / Router and disconnect all other devices connected to Wifi. Want the maximum bandwidth for the computer being upgraded to Big Sur.

It depends, they could be 32 bit which will not run on Big Sur.
Do you know which Mac OS upgrade beyond Mojave still runs 32 bit or is it all OS beyond Mojave?
Welcome and thank you app :- )).
Good luck and do come back to the ASC Forums when additional questions arise.
Catalina and above Only Support 64 Bit everything - not way around that.
To check for 32 bit applications before moving up to Catalina or beyond - Go64 is Trusted and Directly from Developers
I am contemplated updating from Mojave to the latest Big Sur. Has anyone experienced difficulty with any of their existing apps after upgrading
