It was a ~8 year old mix and mesh of tech was not really fixable. We also got too many requests for enterprise clients for Java. And that would have been impossible. We more than doubled in revenue after the rewrite because now we could go for fortune 500 countries.

It was a different time: the product was a combi of perl, php, c++. And then the business world, at least here, went over to java backends.

Many thanks for the explanation. If the product is built using different tech from what you want to use then a rewrite does make a lot of sense.

Cannot edit anymore but: countries is meant to be companies.
