In reality we have to make choices where we DO spend time. There is still a mile

of code out there being used live which is running perfectly on the PHP5.2

before we get around to 5.5.
Why do you change the infrastructure if the code does not need it? I mean, provide the infrastructure the code needs and done. There is more than one vendor that offers support for PHP 5.2 infrastructure in the market. What's the deal?


The point here is supporting customers that I've 'acquired' who are currently hosted on services that control that infrastructure. The long term aim is to move them to servers under our control, but in the meantime until contracts run out we have to live with such activity as 'We will be updating to PHP5.3 on the 1st April'. The problem now is how to deal with that situation, and paying up outstanding contracts may be the solution. The code needs updating, and updating to 5.4 would be useful, but short term everything needs testing and fixing for PHP5.3 :(

The whole reason that ISP's are currently moving from PHP5.2 to PHP5.3 rather than PHP5.4 is that there is a better chance that their client sites will continue to work.
