quick check in advance of upgrade

[valan]

1. Is PW 3.x compatible with PHP 7?

2. Would you recommend PW 3.0.18+ in production? E.g. is it too "dev" or already "prd"?)

3. Any known PW-related issues with migration from myisam to innodb?

4. Pros/cons of switching to nginx + mysql + php-fpm? (apart of lack of support, e.g. need to maintain config manually with each upgrade)

P.S. Currently site is running on PW 2.7.2, MySQL 5.6.29, db by default myisam, PHP5.5, Apache 2.2.22, OS Debian 7

Hi,

1. Is PW 3.x compatible with PHP 7?
I"m not yet using PHP7, however ProcessWire 3.x runs on it and I've been reading reports in the forum to confirm it. But watch out for modules you might have that might have trouble running on it, e.g.:

2. Would you recommend PW 3.0.18+ in production? E.g. is it too "dev" or already "prd"?)
Probably it also depends on the modules you use, such as anything not compatible with the new ImageField module: https://processwire.com/blog/posts/major-images-field-upgrade/

3. Any known PW-related issues with migration from myisam to innodb?
Here is the related blog entry:

Never used it, so I skip this one
