The question didn't say anything about being retrospective!
I won't question your decision to build your own CMS back then, but if you chose to do so today, then I would fire you without a second thought, hence compatibility is an important factor.
I find that somewhat amusing. Are any of the CMSs you can obtain instead of doing your own decent value for money? Will the long term cost of ownership be acceptable if you do it yourself? Will it if you buy instead? It will of course depend very much on your requirements, on whether you can buy something that meets them, on suppliers' prices, and perhaps on what the charge for customisation of a CMS that almost fits would be. And of course the requirements may include flexibility and enhanceability which mill be an issue with some bought systems and also with building your own if you don't have the right sort of development arm. You may even to look at commissioning a software house to create a new CMS for you.
Often build or buy decisions require careful thought, not a prejudged "always buy if there's anything for sale" or "always build because we'll make a better job of it", either of which could be a fatally flawed decision. I would value someone biased towards one answer much the same as someone biased to wards the other - both fail the simple test of being able to answer the question in front of them based on the requirements, the facts, the evidence rather than on their prejudices, so I wouldn't want to allow them to occupy a position where they could influence such a decision.
