Zend Server for IBM i version 2020 is was our first version for IBM i to use an RPM package instead of a Licensed Program for distribution. It is was also our first version to be compiled with the 64 bit compiler. Zend Server for IBM i version 2021 continues to use this new installation method. It can be installed on the same partition as other older versions of Zend Server (prior to 2020) to allow side by side testing before using the new version for production. To upgrade from earlier versions will require a migration. This article provides some notes to help you get started with this task.

| For the purposes of this article, we have written Zend Server 8 when we mean Zend Server 6, 7, or 8. It just seemed cleaner. In some areas we just say Zend Server 2019 when we mean Zend Server 9, 2018, or 2019. And we sometimes just say 2021, when we mean 2020 or 2021. |

Versions 8 and older use a library named ZENDSVR6 and uses directories /usr/local/zendsvr6 and /www/zendsvr6. Versions 9 and 2019 use a library named ZENDPHP7 and uses directories /usr/local/zendphp7 and /www/zendphp7. Versions 2020 and 2021 use a library named ZENDPHP74 and uses directories /usr/local/zendphp74 and /www/zendphp74. |

Install Zend Server 2020 2021 for IBM i
Copy Applications and Other Content to Zend Server 20202021
The simplest installations typically have PHP scripts and other content in the /htdocs directory for the Apache instance. This content can simply be copied to the new /htdocs folder.
...
You should now be able to execute your /htdocs scripts in Zend Server 2020 2021 by changing the port. For example, if you had a script '/www/zendphp7/htdocs/hello.php', using Zend Server 2019 you could run it in your browser at this address:
...
You could copy the script into '/www/zendphp74/htdocs/hello.php', grant user QTMHHTTP *RX permissions to it, then run it using Zend Server 2020 2021 at this address:
http://<your i5 ip address>:10100/hello.php
If you have any deployed Virtual Hosts, Libraries, and/or Applications in an earlier version of Zend Server, simply deploy them in Zend Server 2020 2021 using the User Interface.
...
| Info | ||
|---|---|---|
| ||
| If any of your Virtual Hosts are using ports other than the defaults, remember they cannot use the same port while both your previous version of Zend Server and Zend Server 2020 2021 are active. Temporarily assign different ports for use in Zend Server 2020 2021 while testing. You can change them later when you go into production with Zend Server 20202021. |
Change the Path for PHP-CLI Calls
...
/usr/local/zendphp7/bin/php-cli
And for For Zend Server 2020 2021 you will use:
/usr/local/zendphp74/bin/php-cli
...
Zend Server does not support any Apache instances other than the default (ZENDPHP74 for ZS 20202021, ZENDPHP7 for ZS 9, 2018 or 2019 and ZENDSVR6 for ZS 8). We do have customers who have implemented additional Apache instances by adding a FastCGI configuration to these other instances. If you have any such instances, you can redirect them to version 2020 2021 by changing any occurrences of '/zendsvr6' or '/zendphp7' to '/zendphp74' in the fastcgi.conf for that instance. However, you might need to do other things, and it is easy to mess this file up, so please be careful. This activity is not covered under your Zend Support subscription, so please be sure you know what you are doing, or have whoever set this up for you in the first place come back and make the needed changes.

http://<your IBMi ip address>:10101
Review Changes for PHP 7
Each point release of PHP has migration notes related to the previous version. So for example, migration notes for PHP 7.0 show changes that would need to be made to PHP 5.6 code. So, if you are moving from PHP 5.5 to 7.3, you would need to review the migration notes for PHP 5.6, 7.0, 7.1, 7.2 and 7.3. So, how far you are coming determines how far back you need to go. Zend Server 2020 2021 offers PHP 7.1, 7.2, 7.3, and 7.4. Here are the links:

Before you go into production with Zend Server 20202021, test everything. Test until you are sure everything works. Test until you know everything works. Test until you know that you know that everything works. If you have never built any kind of test plan to exercise your entire site, now would be an excellent time to do that. This article is just a guide to the most common considerations for the migration. We can't think of everything. The only way to be sure you have taken care of everything is to verify that you have taken care of everything. Test it all.
