V3.0 Dead Hot Summer: Do You Need a New Save (Wipe) or Can You Continue?

Updated August 15, 2026. V3.0 has been stable since June 29 and V3.3.0 is the current stable build; the wipe-vs-continue reasoning below still applies to any V2.6 server moving up to the 3.x line.

Moving from V3.0.1 to V3.1.0 "Henpocalypse" stable? No wipe needed. The Fun Pimps confirm 3.1.0 saves are compatible - a new game is not required (a fresh world is only "recommended," as always). Back up first with the in-game Manage Saves function, then update. 3.1.0 also fixes a V3.0 save-corruption bug (the "EndofStreamException" from converting copies of saves), so if you were nursing a flaky 3.0 save, the experimental branch may be the thing that stabilizes it. This is a different decision from the V2.6-to-3.0 jump below, where the worldgen rework makes a fresh world the stronger call.

Short answer: you do not have to wipe. Old V2.6 saves technically load in V3.0, and V2.6 server continuation is officially supported. But V3.0 reworks world generation, so a brand-new world is the cleanest start, and a fresh RWG world is strongly recommended. Server admins should plan a wipe and must migrate their config: more than two dozen legacy serverconfig.xml properties are replaced by a single SandboxCode property, and an un-migrated server silently runs default rules. So the honest version is: continuing works, a fresh world is better, and there is one mandatory migration step either way.

We know "start over" lands badly. The most common sentiment in the launch threads is save fatigue - "I love the update but I lack the drive to start over again." That is a real cost, and it is fair to weigh your community's history against fresh-world content. This guide gives you the decision straight, plus the middle paths that let you keep your old world and still see the new stuff.

The case for continuing (no wipe)

  • It is officially supported. Old V2.6 saves load in V3.0. Recreate your legacy settings in the in-game Sandbox Options menu, paste the generated code as the SandboxCode property, and your world carries forward - the full procedure is in our SandboxCode migration guide. The one trap: an un-migrated config silently runs default rules, which is how a hardcore server wakes up casual.
  • The sandbox layer works retroactively. The 150 sandbox options, the new rule controls, and item magnitude on new loot apply to your existing world immediately. A continued server still gets most of what makes 3.0 interesting.
  • Your community's bases are your retention. Same calculus as every wipe: history keeps the regulars, and save fatigue is real. If your group is tired of starting over, continuing is a legitimate choice, not a compromise.

The case for a fresh world (recommended)

  • V3.0 reworks world generation. This is the core reason a brand-new world is the cleanest start. A fresh RWG world is strongly recommended so the new terrain rules, biome layout, and POI placement generate the way TFP intended rather than being patched onto an old map.
  • New POIs generate in new terrain. 60+ new POIs and the Sign-Tech overhaul are the visible newness; an extensively-explored map shows them only in unexplored or newly generated areas. A fresh world means the full content from the start.
  • The preset moment. Launching a fresh world with one of the V3.0 challenge presets (see the presets guide) is a clean server identity that a continued world cannot adopt mid-story - death rules and progression options bite differently on day 200 than day 1.
  • The population wave. A 3.0-scale update is the biggest player-return window since 2.0; fresh-start servers capture returning players who will not join a world where established players already own the map.

The middle paths (keep your world and still see 3.0)

  • Season it: archive the V2.6 world (final backup, downloadable), open a fresh 3.0 world as a new season with a preset. The wipe-as-ceremony pattern communities accept, and it answers the save-fatigue problem - the old world is preserved, not destroyed.
  • Two worlds for launch month: continue the V2.6 save for the regulars, open a fresh preset server for the wave, merge attention later.
  • Continue now, wipe at stable: keep the old world on your current build for now, then treat the move to the V3.0 stable line as the wipe moment - this also dodges experimental-cycle instability on a fresh map everyone is invested in.

The update-week checklist (either path)

  • Backup, restore-tested, before touching the version. Saves do not load backward; the backup is the only rollback.
  • Record your V2.6 settings before updating - you will recreate them in the Sandbox Options menu and migrate them into one SandboxCode property (the legacy serverconfig properties are removed). This step is mandatory whether you wipe or continue.
  • Match your client and server to the same branch. A V3.0 experimental client cannot join a V2.6 stable server and vice versa - the launch window is generating "incompatible version" errors for exactly this reason. See our version mismatch guide if players cannot connect.
  • Modded servers: wait for your critical mods. The V3.0 mod compatibility guide covers what breaks; overhaul servers wait longest.
  • Pin your current version until you choose to move. Nothing happens to your server until you flip the branch, so you control the timing of the update.

FAQ

Do I need a new save for 7 Days to Die 3.0?

No, you do not have to start a new save. Old V2.6 saves load in V3.0 and continuation is officially supported. However, V3.0 reworks world generation, so a brand-new RWG world is the cleanest start and is strongly recommended. Server admins should plan a wipe, and either way you must migrate your config to the new SandboxCode property.

Will my 2.6 world work in 3.0?

Yes. A V2.6 world technically loads on V3.0 and the sandbox layer applies to it retroactively. The catch is that 60+ new POIs and the reworked terrain only appear in unexplored or newly generated areas, so an old, well-explored map will not show the full V3.0 content. For that reason a fresh world is recommended.

Do I have to wipe my server for 3.0?

It is not strictly required, but it is recommended. Because V3.0 reworks world generation, a fresh RWG world gives you the new terrain, POIs, and rules the way they were intended. If you want to keep your community's history, you can continue the V2.6 world or use a middle path such as archiving the old world and opening a fresh seasonal one. In every case you must migrate your serverconfig.xml to the SandboxCode property.

What is the SandboxCode migration and is it mandatory?

Yes, it is mandatory. V3.0 replaces more than two dozen legacy serverconfig.xml properties with a single SandboxCode property. You generate the code in the in-game Sandbox Options menu and paste it into serverconfig.xml. An un-migrated server silently runs default rules instead of your intended settings, which is how a hardcore server can wake up casual after the update.

When does V3.0 Dead Hot Summer release?

V3.0 Dead Hot Summer released as stable on June 29, 2026 (current 3.0-line stable: V3.0.1), and V3.3.0 is the current stable release. V2.6 is a legacy branch.

I do not have the drive to start over again. Is continuing a valid choice?

Yes. Save fatigue is a real and common reason to continue, and a continued V2.6 world still gets the sandbox options and item magnitude in V3.0. If you want the new world content without fully losing your old base, archive a final backup of the V2.6 world and open a fresh seasonal world alongside it.
