unfortunately my experience is that one have to carefully look on the typesetted output to check the differences. what i can advise: - before migration make export to both .pdf and .tex. pdf for having output to post, .tex to have something which more stable format over the time. - backup all this - except comparing output one can check the intermediate .tex by means of diff, but don't go this wat unless you are friend with latex and diff tools :) - consider whether not to wait some month more to migrate directly to 1.6. when i was thinking some time ago about these format migrating issues i realised there is really no single format maybe except plain ASCII text file which is stable enough that after some 10 years i will be able to read appropriately for sure. even the most stable tex files have problems because tex compilers are evolving in subtle ways and all the tools around for e.g. pictures or bibliography are in movement too. not a single thing you can stick on :( pavel
