How to upgrade the go version in a go mod

What is the proper way to upgrade the go version in a go mod, specifically 1.13 to 1.14?
Do you simply edit the go.mod file and change go 1.13 to go 1.14?

I'm not asking about how to edit the go.mod file, I'm asking if it is proper to simply change the go version in the go.mod file, and everything else (all the dependencies) is still ok for the project?

Command go: Edit go.mod from tools or scripts:

Usage:

go mod edit [editing flags] [go.mod]

Edit provides a command-line interface for editing go.mod, for use primarily by tools or scripts. It reads only go.mod; it does not look up information about the modules involved. By default, edit reads and writes the go.mod file of the main module, but a different target file can be specified after the editing flags.

...

The -go=version flag sets the expected Go language version.

So simply:

go mod edit -go=1.14

But you may also edit go.mod manually, it's a simple text file. go mod edit is primarily for scripts so making changes to go.mod can easily be automated.

I you are working with go.work you can do it with this script. It will change all child mod version also

#!/bin/bash

# Function to recursively upgrade Go modules
upgrade_go_modules() {
  # Prompt user for Go version
  read -p "Enter the Go version (e.g., 1.17): " go_version
  if [ -z "$go_version" ]; then
    echo "Go version not provided. Exiting."
    exit 1
  fi

  # Update go.work file in the root directory
  sed -i "s/go[[:space:]]\+[0-9]\+\(\.[0-9]\+\)*$/go $go_version/" go.work

  # Upgrade Go modules
  for mod_file in $(find . -name "go.mod"); do
    dir=$(dirname "$mod_file")
    echo "Updating Go version in $dir"
    (cd "$dir" && go mod edit -go="$go_version")
  done
}

# Main execution
upgrade_go_modules

In addition to the provided solutions for updating go.mod file,

If your project is dockerized, don't forget to update the docker base image as well, e.g.:

FROM golang:1.17 AS build

to

FROM golang:1.20 AS build

The answers supplied here helped me alot. But a little adjustment may be due especially for Windows users.

I used on the command prompt:

go mod edit -go 1.17

And not:

go mod edit -go=1.17

Note the omission of ''=" sign.

The other answer is good, but as another method, say you have this:

module north

go 1.13

you can just delete the go line, and run go mod tidy. Result:

module north

go 1.16
