WCL Patreon Benefits vs Already uploaded logs

Hey there!

I am seriously considering subscribing to WCL, but I have a question about logs already uploaded by a guild member.

In order to get those logs preserved, will I need to sub to the 10$ monthly? As the current GM, I would like to have all the logs preserved indefinitely; but I am not the one that has been uploading those logs. I know that all reports for all guilds will get preserved with the 10$, but that’s a little excessive considering that I only raid with one guild.

If I choose the Gold option, will I need to re-upload those logs or just kiss them goodbye down the road?

Thanks ahead of time!
