DnD5e Higher level content / at level 13 now what?

Not sure if this is the right forum for this question. I have been in a D&D 5E campaign for a few months and we will likely need a few more months to finish it up.  We started at level 1 and expect to end up around level 12 or 13. My DM really likes the modules here on roll20 marketplace as everything is setup, he is working so he doesn't really have the time to make his own campaigns. Most if not all modules in the marketplace appear to start at a low level 1-4 and carry you up to the 12-15 range. At that point, do you retire your character and roll a new one for the next campaign? Do you take an existing campaign and increase the difficulty of the encounters? I wanted to ask the community what the general practice is.  I have grown fond of my character and hate to just retire him. I guess a followon question would be, if there are DMs that create higher level content and share (either free or for a charge) their work. Thanks

The over-simplified answer is: the group does what it wants. If you want to continue the adventures of your characters, then that is what you do. If you want to start a new story with new characters, then that is what you do. Both are great choices and are equally valid. If your DM is short on time, adjusting an adventure might not be the best route as rebalancing encounters can take a bit of time. There are a few high-level adventures on Roll20. The&nbsp; War of the Burning Sky &nbsp;campaign saga starts at level 3, but it has several points where a DM could jump into the campaign at a higher level to play an abridged campaign. However, I would recommend running the complete campaign as it has a deep and rewarding story. <a href="https://marketplace.roll20.net/browse/publisher/230/ancris-it" rel="nofollow">https://marketplace.roll20.net/browse/publisher/230/ancris-it</a>

Check out Dungeon of the Mad Mage, which is available on the Marketplace for Roll20. That's designed to take characters from level 5 to 20, so you'd probably just give your players a quick summary of what happened on the first 13-ish levels, and then jump them into the adventure where the dungeon level matched their character levels.
