Upgrade Robohelp project version 5.0.2 to 8.34

As Peter has previously mentioned, because your version is so old I suspect there is a lot that won't upgrade properly. The reason I think this is I'm sure sometime after X5 (maybe RH7 or 8-ish?) there was a behind the scenes code refresh (which, among other things, removed kadov tags, a bane of our existence 🙂 ). Then RH2019 New UI completely changed the behind-the-scenes code again. I'm not sure Adobe would have written/included scripts to convert the kadov era hmtl code. But only Adobe can say for sure.

OK but that is a seriously old version and I'm surprised it is still running on modern operating systems. According to the Adobe site it is only compatible with Windows XP, 2000, NT 4.0, ME, and 98. If you have X5 on something later, there could have been corruption causing this problem. If you are still on one of those versions I would be very surprised RoboHelp even installed.

As I said earlier, I think now it's a case of manually fixing the IDs if that is the only issue or going to Adobe Support.

Looking at the thread again, I see you did refer to a Classic version so maybe it was X5 to 2020.8? Please clarify.

If it was from X5 then I think you may just have to reassign the IDs but check with Adobe Support, they may have a backdoor way of fixing it. See https://helpx.adobe.com/contact/enterprise-support.other.html#robohelp for your Adobe Support options.

I think there may be some confusion because you have clipped the version numbers. I read it as Version X5 rather than 2020.5. So you mean 2020.5 to 2020.8?

The most important parts are the Version, 2020, and the next number which is the update. The build is less important.

@Jeff_Coatsworth suggested going via 2019 because at one time that did fix upgrade issues. However the issues it fixed have now been built into the upgrade process so I don't think it will help.

Your TOC is blank. What about the Contents Panel? do the topics show there. If they do, is the mapping information showing there?

When you say you are upgrading from Version 5, do you mean X5? That is an extremely old version so it wouldn't surprise me the upgrade is failing. I'm not sure what has gone wrong and I think you may need to go to Adobe Support. See https://helpx.adobe.com/contact/enterprise-support.other.html#robohelp for your Adobe Support options.

It may be a case of fixing it all manually.

Sorry, as I'm still stuck on RH11, I don't have a subscription to go and look at to indicate where you can get the RH2019 versions - I just know that they are part of the subscription. Maybe this page will help? https://helpx.adobe.com/download-install/kb/downloaded-older-app.html

You should be able to view the log file that it created. But with a project that old, I would suggest trying a Classic to Classic upgrade path - your 2020 subscription includes RH2019 Classic and RH2022 (the latest). I'd download both & try the RH2022 one first. If you still strike out with that, try a copy of the old Classic project upgraded to RH2019 Classic and then upgrade that to RH2022.
