I have an application that uses pgRouting v1. I was wondering if it is possible to easily migrate from version 1 to version 2 of pgRouting. I noticed that the pgRouting v2 announcement stated that v2 is not baskwards compatible, is there any guide / list of steps to get it working using v2.
I already have postgres 9.3, postgis2.1 and pgrouting 2.0 installed (the ones available in the Ubuntu 14.04 repositories).
I'm reading the documentation for 2.0 and will read the workshop, but it does not look like there is a migration chapter.
Wrapping up, is there (or will be) any migration guide?

No there is no migration guide.
Anyone, who wants to contribute one is welcome.

Really is there already pgRouting for 14.04?

A few hints maybe:
- If you only used "core" functions of Dijkstra or A* you should be OK
to change the function name and make small modifications as the column
names of the result are slightly different.
- If you used Shooting Star algorithm, then you need to look at TRSP,
because Shooting Star was removed
- If you used wrapper functions, then you now need to write them
yourself.

Do not expect this file to work? but you can use it as an example of how you some of the old commands could be mapped to the new ones. This file has not been tested or validated in any way, but I put it together with the thought that it might help someone with understanding how to migrate 1.x to 2.0.

Ok, at least for me has been really easy. In my case i just changed the shortest_path_astar method to pgr_astar and done a selection over the result set of that to just select id1, id2 and cost (leaving out seq), and with that the result of the v1 and v2 are the same.

Well, it is in Debian Sid (unstable), Ubuntu 14.04 pulled it from there. (So yes is there in the development branch and it’s really easy to set up a pgRouting enviroment, just a package, easy, easy).

Wow, I didn't know someone already added pgRouting to Debian.
