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.<br clear="none">
</blockquote><div><br clear="none"></div><div>No there is no migration guide.</div><div>Anyone, who wants to contribute one is welcome. ;-)<br><br>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.<br></div><div> </div><blockquote class="yiv6776247601gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">

I already have postgres 9.3, postgis2.1 and pgrouting 2.0 installed (the ones available in the Ubuntu 14.04 repositories).<br clear="none"></blockquote><div><br clear="none"></div><div>Really is there already pgRouting for 14.04?</div><div> <br>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).<br><br></div>

I'm reading the documentation for 2.0 and will read the workshop, but it does not look like there is a migration chapter.<br clear="none">
<br clear="none">
Wrapping up, is there (or will be) any migration guide?<br clear="none"></blockquote><div><br clear="none"></div><div>A few hints maybe:</div><div><ul><li>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. </li><li>If you used Shooting Star algorithm, then you need to look at TRSP, because Shooting Star was removed</li><li>If you used wrapper functions, then you now need to write them yourself.</li></ul><div>Best,</div></div><div>
