Thank you, Viswasruti, for the comment migration of all three stories. I checked the comment migration for Antarāya-timir'opaśāntaye, and it worked beautifully on the whole.
I will mention a few general issues that the technical team might fix to improve the comment migration process for everyone's fan fictions.
1. Paragraph breaks in posts are lost during migration. Could the migration process recognize and retain paragraph breaks, including blank-line-in-between breaks? I edited my own comments to reintroduce the breaks.
2. Hyperlinked words within posts are totally deleted when they become comments. Could the visible text be kept even when the URL is deleted? (When I copy-and-paste from a post into a comment-reply, hyperlinks become plain text automatically. Why not during comment migration?) I edited my own comments to retype the missing words so that sentences make sense again.
3. Some comments have metadata at the end of the text: who posted and the date and time. I suspect that this is caused by the process determining that replies posted before Chapter Two should become comments under Chapter One, and replies posted after Chapter Two should become comments under Chapter Two.
Examples:
https://www.indiaforums.com/fanfiction/chapter/21774
has a newest migrated comment ending with "Radiant_Eyes_2021-08-05 12:15:53"
https://www.indiaforums.com/fanfiction/chapter/21775
has an oldest migrated comment ending with "hapc2021-08-22 18:27:55"
4. Posts that are too long appear as comments that are cut off at the character limit, even in the middle of a word. I edited my own comments to continue in a self-reply. Could the migration process include checking the length of each post, and if it's too long, splitting it at the previous paragraph break or other punctuation to continue in a comment-reply?
5. Some emojis in posts appear in comments, but "" or "
" or "
" doesn't appear for some reason.
In response to your question, "is it possible for you to delete those or not??" - as the author, I don't have the privilege to delete anyone else's comments. I see the Edit/Delete wheel next to my own comments, but for everyone else's comments, there's only a Report flag button.
I will now check the migrated comments for the other two stories, and if there are no problems, I will just edit this post to say so, since I don't want to spam the thread. Thanks again for the help with all three stories.
Edited to add: The non-comment posts that were off-topic in the thread did get migrated in spite of my request to exclude them. It's not a big problem for me, but it would be good if FFEditors had the ability to de-select posts during comment migration.
