= **Upgrading EasyRSA** #ersa-up23-top

----

**Note**: This wiki is a ''work in progress''.

This page describes the EasyRSA PKI upgrade process:
  EasyRSA PKI version 2 to EasyRSA version 3, see below. \\
  [#ersa-up33 EasyRSA CA version <3.0.6 to EasyRSA version >3.0.6]

[[TOC(notitle, inline)]]

----

== Usage #ersa-up23-usage

To perform the upgrade:


1. {{{ ./easyrsa upgrade pki }}} \\
  This will upgrade a version 2 PKI to version 3. \\
  This upgrade will also perform the CA upgrade below. \\
  The CA is set to allow duplicate certificates to allow for for renewal. \\
  The PKI is not changed only copied.

2. {{{ ./easyrsa upgrade ca }}} \\
  The CA is set to allow duplicate certificates to allow for for renewal. \\
  The PKI is not changed.

To automate this upgrade use `--batch`

== Steps #ersa-up23-steps

These CHECKS will be made if you upgrade now:

 Before ANY changes are made a test run will be attempted ...

   * Verify: new PKI dir does not exist and will not be over written.
   * Verify: new backup PKI dir does not exist and will not be over written.
   * Verify and Source the current PKI settings: ./vars or ./vars.bat
   * Verify the current ca.crt

Then:
 * CONFIRM NOW THAT THIS IS THE CORRECT ca.crt and continue or quit

These CHANGES will be made if you continue:

 Before ANY changes are made a test run will be attempted ...
 * Complete backup of the current PKI to ./VERY-SAFE-PKI
 * Create new PKI dirs for use with EasyRSA-3
 * Copy required working database files to new PKI
 * Copy current PKI to new PKI
 * Update the CA to allow duplicates for renewal
 * create new openssl-easyrsa.cnf file
 * Remove EasyRSA-2 program files
 * Build new EasyRSA-3 vars file


== Setup #ersa-up23-setup

 1. You must install a new copy of EasyRSA v3.0.7 or above
 1. Copy your existing EasyRSA v2 files and directories into `./easyrsa3` \\
    Your `./easyrsa3` directory should now look ''something'' like [#ersa-up23-before Before] below:
 1. Linux: run `./easyrsa upgrade pki`
 1. Windows: run `easyrsa-start.bat` and then `./easyrsa upgrade pki` \\
    If you have trouble starting EasyRSA-v3, please consult the relevant documentation. \\
    Your `./easyrsa3` directory should now look ''something'' like [#ersa-up23-after After] below:

== Fails #ersa-up23-fails
**Correct the error reported first.**

Before you can try the update again you MUST remove these two directories:

 * `./easyrsa3/pki`
 * `./easyrsa3/VERY_SAFE_PKI`

You **may** also need to remove the newly created vars file at:

 * `./easyrsa3/vars`

If you find this warning at the top of the ./vars file then it is safe to remove:
 {{{

=== Incompatible `vars` file #ersa-up23-fails-bad-vars

The the `vars` file in place uses export which Easyrsa3 does not support.

=== Too many `vars` files #ersa-up23-fails-vars-bat

There exists a `vars` file and a `vars.bat` file. Only one of these files may exist.

=== CA certificate does not match `vars`/`vars.bat` file settings #ersa-up23-fails-ca-vars

The current CA details do not match the `vars` file in place.

== v30x to v306 #ersa-up33

Only one change is required:
  `pki/index.txt.attr` \\
  Required: `unique_subject = no`
