We're looking at the pros and cons of moving from Microsoft IIS running .asp to a LAMP environment. Without going into details there are enough compelling reasons related to our specific scenario to consider this move. There is little or no actual .asp programming on the current site that we need to duplicate on the current site. For the most part it's a static site that happens to be .asp. We're about to make it a dynamic site so it seems like a reasonable time to choose our preferred development environment.
I'm not well-versed in the technical aspects but the developer feels that they can address my concerns, most of which are related to preserving search engine performance. We have around 250 pages that have a firm footing in Google, etc. and we get a steady flow of traffic through those pages.
I've read some of the threads about moving a site to a new server, and feel comfortable with that scenario, but changing platforms seems like a double whammy to me.
I'm told that in the LAMP environment we can continue to serve up the old .asp file names so as to preserve our current search engine foothold. However, if feasible I'd like to replace those with .php pages over time.
1. Is this true?
2. Are there other factors I should be aware of in planning this transition?
3. Any other red flags that our developer should address?
