This seems crazy, but I can't seem to open documents saved in the new 2021 vs 16 of InDesign with just the previous version, i.e 15.1.2, or 2020 - it is asking if I wan't to convert them and potentially loose data, formatting, etc.
This was the case when I was trying to open old CS5 files in CC - converting to IDML files first, but surely not with just one version back? I can't update my InDesign to vs16 as have an old 2011 imac which can't update OS beyond High Sierra, and therefore can't update to the latest version of InDesign.
Is this right? Any thoughts or ideas would be great!
That has ALWAYS been the case with INDD files. There has never been a time where you could open a file created in a newer version. With CC you get the option for Adobe to do the conversion for you but make no mistake, it's no different than having someone else save it as an IDML file.
There should have been no need to convert old files to IDML to open them in newer versions of InDesign.
One more thing...you can avoid all this by upgrading your operating system.

This is how InDesign works, and has worked for years.
Each new version of InDesign changes the file format to the newer version. When you open a file from an earlier versions (i.e, 2020) in a newer version (i.e., 20210) you will see the word CONVERTED by the filename. This is to protect the file, and encourages you to save it under a new name. If you overwrite the file, you will have converted it to the newer version, and the older version can't reopen it without converting it back.
Since it appears you have already done that, go ahead and let InDesign convert it back for you, then review it closely for issues. It will likely be just fine.
>> This seems crazy,
This craziness was always as Barb already says to you. Do you need to convert file or you already do idml on your side?
Thanks for all your responses, although I am still a little confused!
When working from home on Adobe CC, if I had files created at my place of working, using the much older CS5, I would need to IDML them in order to then open them on CC.
If, however, I was simply doing the smaller updates every few months, or more major updates annual, at home on CC, it would never ask me to 'convert' these files before opening?
This issue was bought to my attention earlier today by our freelance subeditor, who recently updated to InDesign 2021, and came across this issue trying to open our 2020 files. Again, he had not seen this happen before.
And yes, I know I could avoid it by updating my operating system, if I could. As stated in my original post, my iMac is mid 2011, and therefore High Sierra is a far as it goes. I would consider buying a new Mac, but was hoping for a redesigned machine, which I gather might be coming early next year...

This is another situation. Are you sure? Give us here example of your 2020 indd file that can't opened with v2021 (through some dropbox or yadisk service)
Please post one of these files and supply a dropbox link. While I have read of some instances of early files not being able to be opened in newer versions those are far and few between.
I also am having problems opening a very large file (60mg) from a previously saved InDesign v16 back to 15.1.3 as an .idml, and saved over it in the older InDesign. Now I can't open the file in either version. I work from home on a newer Mac, but my office Mac cannot be upgraded. I have an enormous amount of time dedicated to this file and I hate to go back to an older version. Any helpful ideas are greatly appreciated.
