Upgrade from High Sierra to Catalina
is my late 2011 MacPro that has High Sierra 10.2.6 compatible to download OS Catalina?

Depending on which system and mac you could mean by what you wrote,
the next supported macOS could be 10.14.6 Mojave. ~ The mac is too old to
run Catalina. -- Perhaps may not support Mojave either.
{..Your mac pro (tower) would likely require a 'Metal compatible' graphics card..}
If you meant a portable macbook, then no. This Mojave won't run in 2011 model.
Mac Pro introduced in 2013, plus mid-2010 or mid-2012 models
with a recommended Metal-capable graphics card.
"..To find your Mac model, memory, storage space, and macOS version, choose
About This Mac from the Apple menu . ~ If your Mac isn't compatible with
macOS Mojave, the installer will let you know.."
Link to read about and download Mojave 10.14.6 Installer (it then can get the
hours-long wait for system files from Apple servers) here:

"If you have hardware or software that isn't compatible with Mojave, you might
be able to install an earlier macOS, such as High Sierra, Sierra, or El Capitan."
Good luck & happy trails!🌞🎣
